Peroxidase-like reaction process involving o-phenylenediamine (OPD) and silver nanoprisms in the presence of hydrogen peroxide (H2O2) was monitored using time-resolved ultraviolet–visible (UV–Vis) absorption spectroscopy. The oxidation of OPD and etching of silver nanoprisms were investigated by analyzing the dynamic spectral data. Two-dimensional correlation spectroscopy (2D-COS) and principal component analysis (PCA) were employed to gain insights into the correlation between catalytic oxidation of OPD and etching of silver nanoprisms. It was found that OPD offered significant protection effect for silver nanoprisms so that morphologies of silver nanoprisms maintained at the beginning period after addition of H2O2. Moreover, silver nanoprisms accelerated the oxidation of OPD by H2O2, demonstrating enzymatic mimicking activity of silver nanoprisms. The combination of time-resolved UV–Vis absorption spectroscopy and spectral calculation methods could be used for exploration of complex reaction systems with spectral variations.

Palladium nanoparticle (PdNP) loaded cotton fabrics were successfully prepared through in situ synthesis of PdNPs via heating. The resulting PdNP-treated cotton fabrics showed color originated from the localized surface plasmon resonance (LSPR) effect of PdNPs, with satisfactory color fastness to washing and rubbing, and enhanced UV protection properties. The PdNP-treated cotton greatly accelerated the reduction reaction of 4-nitrophenol (4-NP) by sodium borohydride, exhibiting distinct catalytic activity. More importantly, the PdNP-treated cotton fabric displayed enzyme mimicking activity to catalyze the oxidation of a chromogenic enzymatic substrate (3,3′,5,5′-tetramethylbenzidine) in the presence of hydrogen peroxide, which provides a visual sensing platform for hydrogen peroxide. This work demonstrated a versatile approach to fabricate PdNP-treated cotton fabrics with multiple functions. This study on the surface modification of cotton fabrics with PdNPs could promote the practical applications of functional fibrous materials in catalysis and sensing fields.

Fluorescent and robust fibers based on gold nanoclusters-loaded alginate were successfully prepared by wet spinning of gold nanoclusters and alginate. The relationship between process conditions, mechanical properties, and fluorescent properties of fibers was investigated. The as-prepared fibers exhibited high mechanical strength (up to 7.09 cN/dtex) and remarkable red emission under ultraviolet excitation. The fibers could be used as a simple, low-cost, and high-selectivity fluorescent sensor for detecting Cu2+ and Hg2+ among various metal ions in aqueous solution, with a detection limit as low as 187.99 nM for Cu2+ and 82.14 nM for Hg2+, respectively. Furthermore, the novel fluorescent fibers were used as an anti-counterfeiting label through knitting into textile materials. The wet-spun functional fibers may be applied to the design of smart wearable sensors and flexible optical sensors.

Eggshell membrane (ESM), which consists of unique interwoven shell membrane fibers, provides a unique supporting platform for functional nanoparticles in catalysis and sensing. This work reports a novel strategy for fabricating sunlight-driven photothermal conversion composite membranes by loading graphene oxide (GO) and gold nanoparticles (AuNPs) on the three-dimension (3D) network structured eggshell membrane. Surface morphologies and chemical elements were characterized by scanning electron microscopy and X-ray photoelectron spectroscopy. High photothermal conversion under simulated sunlight irradiation, which may be caused by the synergistic effect of GO and AuNPs, was achieved by coating both GO and AuNPs onto ESM. The temperature of ESM modified with AuNPs, and then GO increased from 26.0 °C to 49.0 °C after 10 min of light irradiation. Furthermore, the nanoscaled GO and AuNPs could add benefit to the heating localization of the obtained composite membrane. It is expected this biocompatible ESM modified with GO and AuNPs would have great potential in drug release and photothermal therapy applications.

Dynamic changing process of pH-sensitive anthocyanin solutions was monitored by time-resolved ultraviolet–visible (UV–vis) absorption spectroscopy. Two-dimensional correlation spectroscopy (2DCOS) and principal component analysis (PCA) were further used to investigate the spectral data associated with chemical structure change of anthocyanin. The addition of acid resulted in the narrowing and blueshift of the absorption band of the anthocyanin solution around 528 nm. This may be caused by the formation of flavylium cation from carbinol pseudobase. The addition of alkali led to synchronous changes of the absorption bands around 528 and 607 nm, implying the conversion of flavylium cation to quinonoidal base. 2DCOS data suggested that the peak assigned to flavylium cation during the structural conversion could be located at 520 nm, which was rarely found in the time-resolved absorption spectra. Silk fabric was dyed with anthocyanin and used as a colorimetric pH sensor. The flexible pH sensing fabric showed visual sensitivity to pH changes, with great reusability and stability. The wearable pH fabric sensors fabricated from sustainable and renewable natural biomaterials have potential applications in environmental monitoring, medicine and smart clothing.

After platinum nanoparticles (PtNPs) were in-situ synthesized on silk fabrics through heat treatment, it was determined that the treatment of the silk fabrics with PtNPs imparted multiple functions, including coloring, catalysis, and antibacterial activity. The formation of PtNPs on fabrics was affected by the Pt ion concentration, pH value of solution, and reaction temperature. Acidic condition and high temperature were found to facilitate the formation of PtNPs on silk. The color strength of silk fabrics increased with the concentration of Pt ions. The PtNP treated silk fabrics exhibited reasonably good washing color fastness and excellent rubbing color fastness. The morphologies and chemical components of the treated silk fabrics were analyzed using scanning electron microscopy and X-ray photoelectron spectroscopy. The PtNP treated silk fabric exhibited significant catalytic function and a notable antibacterial effect against Escherichia coli (E. coli).

Nanocomposites consisting of bacterial cellulose (BC) and gold nanoparticles (AuNPs) were successfully fabricated using a facile one-step photoinduction method. Well-dispersed AuNPs were in-situ synthesized on the network of BC hydrogels in the presence of tetrachloroauric (III) acid solution under a xenon light source. BCs were treated with different concentrations of gold ions. The optical features and morphologies of the treated BCs were investigated by ultraviolet–visible absorption spectroscopy and scanning electron microscope. X-ray diffraction and X-ray photoelectron spectroscopy were also employed to characterize the AuNP–BC nanocomposites. The experimental results demonstrate that AuNPs are uniformly dispersed and well-bound to the BC matrix, and the three dimensional porous structure of BC is sustained. The acid condition facilitates the synthesis of AuNPs by using BC in aqueous solution. The AuNP–BC hydrogels were then dried into a transparent nanopaper and used as the surface enhanced Raman scattering (SERS) substrate. The lowest detectable concentration for Rhodamine 6G could be achieved at 0.1 nM. Furthermore, by stamping the nanopaper on a yarn or paper, we established an SERS platform for in-situ detection of trace concentration of dyes on the yarn or paper, enabling its application in forensic investigation and art conservation application areas.

We fabricated a low-cost and efficient composite photocatalyst material, combining eggshell membrane (ESM) and titanium dioxide (TiO2) nanoparticles, through self-assembly method. ESM with 3D porous structures provide scaffolds for TiO2 nanoparticles. Polyethyleneimine (PEI) was used to modify ESM by grafting amine groups. The microstructure and property of the fabricated composites were studied by various characterization methods. The composite was used for the photodegradation of Rhodamine B (RhB). The results demonstrate that the composite catalyst possesses good photocatalytic performance for dye degradation under sunlight irradiation simulated by a xenon lamp. Functionalization based on nanomaterials may promote the applications of ESM.

Biomass disks based on fine powder produced from disposed wool fibers were prepared for surface-enhanced Raman scattering (SERS). The wool powders (WPs) were modified by silver nanoprisms via an assembly method and then pressed into disks using a hydraulic laboratory pellet press. Scanning electron microscopy (SEM), X-ray diffraction (XRD), and X-ray photoelectron spectroscopy (XPS) were used to characterize the WPs and disks before and after treatment with silver nanoparticles (AgNPs). The WPs retained porous structures after treatment with AgNPs. The silver nanoprisms on WPs were observed clearly and the localized surface plasmon resonance (LSPR) properties of silver nanoprisms led to blue color of wool powder (WP). The obtained WP disks with AgNPs were confirmed to enhance greatly the Raman signal of thiram. The SERS disks are low-cost and convenient to use, with high sensitivity. The characteristic SERS bands of 10-8 M thiram can be identified from WP disks containing silver nanoparticles.

Gold nanoparticles (AuNPs) were synthesized in situ on wool powder (WP) under heating conditions. Wool powder not only reduced Au ions to AuNPs, but also provided a support for as-synthesized AuNPs. WPs were treated under different concentrations of Au ions, and corresponding optical features and morphologies of the treated WPs were investigated by UV-VIS diffuse reflectance absorption spectroscopy and scanning electron microscopy (SEM). X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and transmission electron microscope (TEM) were also employed to characterize the WP treated with AuNPs. The results demonstrate that AuNPs were produced in the presence of WP and distributed over the wool particles. The porous structure led to the synthesis of AuNPs in the internal parts of WP. Acid conditions and high temperature facilitated the synthesis of AuNPs by WP in aqueous solution. The reducibility of wool was improved after being converted to powder from fibers, due to exposure of more active groups. Moreover, the obtained AuNP-WP complexes showed significant catalytic activity to accelerate the reduction reaction of 4-nitrophenol (4-NP) by sodium borohydride (NaBH4).

We reported the fabrication of an in situ surface-enhanced Raman scattering (SERS) monitoring platform, comprised of a porous eggshell membrane (ESM) bioscaffold loaded with Ag nanoprism via an electrostatic self-assembly approach. The localized surface plasmon resonance (LSPR) property of silver nanoprism leads to the blue color of the treated ESMs. UV-vis diffuse reflectance spectroscopy, scanning electron microscope (SEM), X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) measurements were employed to observe the microstructure and surface property of Ag nanoprisms on the ESMs. The silver nanoprism-loaded eggshell membrane ([email protected]) exhibited strong catalytic activity for the reduction of 4-nitrophenol by sodium borohydride (NaBH4) and it can be easily recovered and reused for more than six cycles. Significantly, the composites also display excellent SERS efficiency, allowing the in situ SERS monitoring of molecular transformation in heterogeneous catalysis. The results indicate that the [email protected] biocomposite can achieve both SERS and catalytic functionalities simultaneously in a single entity with high performance, which promotes the potential applications of ESM modified with functional materials.

The fast detection and removal of organic dyes from contaminated water has become an urgent environmental issue due to their high toxicity, chemical stability, and low biodegradability. In this paper, we have developed graphene oxide decorated [email protected]([email protected]O) as a novel adsorbent aiming at the rapid adsorption and trace analysis of organic dyes followed by surface enhanced Raman scattering (SERS). The structure and morphology of the nanocomposites were characterized by transmission electron microscopy (TEM), Fourier infrared spectrometry (FT-IR), X-ray diffraction (XRD), and vibrating sample magnetometer (VSM). The obtained nanocomposites were used to adsorb methylene blue (MB) in aqueous solution based onπ-πstacking interaction and electrostatic attraction between MB and GO, and the adsorption behaviors of MB were investigated. Moreover, the obtained nanocomposites with adsorbed dyes were separated from the solution and loaded with silver nanoparticles for SERS detection. These nanocomposites showed superior SERS sensitivity and the lowest detectable concentration was 1.0 × 10−7 M.

A monolithic column functionalized with gold nanoparticles (GNPs) was designed to provide ultrasensitive detection with surface-enhanced Raman scattering (SERS). The monolithic column based on poly (glycidyl methacrylate-co-ethylene dimethacrylate) (GMA-co-EDMA) was served as the enrichment sorbent to concentrate GNPs and targets. We found that 60 nm GNPs-functionalized monolithic columns demonstrated the best SERS enhancement, and the lowest detectable concentration for PATP and CV could be achieved at 10−7 and 10−11 M, respectively. Moreover, the columns exhibit a good reproducibility in both spot-to-spot (∼10%) and batch-to-batch (∼15%). The SERS monolithic column with a high sensitivity and reproducibility has a great potential in the field-based rapid detection of targets in complex real-world samples.
