Several chemo-drugs act as the biocompatible fluorophores. Here, the laser induced fluorescence (LIF) properties of doxorubicin, paclitaxel and bleomycin are investigated. The absorption lines mostly lie over UV range according to the UV-VIS spectra. Therefore, a single XeCl laser provokes the desired transitions of the chemo-drugs of interest at 308 nm. It is shown that LIF spectra are strongly dependent on the fluorophore concentration giving rise to the sensible red shift. This happens when large overlapping area appears between absorption and emission spectra accordingly. The red shift is taken into account as a characteristic parameter of a certain chemo-drug. The fluorescence extinction (α) and self-quenching (k) coefficients are determined based on the best fitting of the adopted Lambert-Beer equation over experimental data. The quantum yield of each chemo-drug is also measured using the linearity of the absorption and emission rates.

Hybrid nanomaterials consisting of multi-walled carbon nanotubes (MWCNT) decorated with palladium nanoparticles are fabricated by the nanosecond laser irradiation of solid foil Pd target submerged in the suspension of MWCNTs in deionized water. The aim is to characterize the hydrogen storage property of laser-induced Pd-decorated MWCNTs for various laser doses. The corresponding structural surface properties as well as the yield of induced Pd nanoparticles on the MWCNTs are investigated by means of several characterization methods. The hydrogen storage measurement was carried out based on the cyclic voltammetric method and discharging curves. In general, the hydrogen storage capacity is enhanced with Pd decoration with respect to the pristine MWCNTs.

Red/blue shifts of laser-induced fluorescence (LIF) are investigated using several guest dielectric nanoscatterers, such as ${\mathrm{TiO}}_2$, ZnO, ${\mathrm{Al}}_2{\mathrm{O}}_3$, and ${\mathrm{SiO}}_2$, in the host Rd6G, RdB, Coumarin 4, and Coumarin 7 ethanolic solutions. A couple of inflection points are identified varying nanoparticle (NP) density into dye solutions based on LIF spectroscopy. The inflection of the spectral shift exhibits that the suspension of NPs in dye solutions significantly involves a couple of competitive chemical and optical mechanisms during photon traveling in scattering media regarding ballistic and diffusive transport. It is shown that the low, medium, and high NP additives in fluorescent suspension induce blue, red, and blue spectral shifts, respectively.

Laser induced breakdown spectroscopy and subsequent acoustic response during microplasma formation are employed to identify cancerous human breast tissues. The characteristic optical emissions identify Ca, Na, and Mg rich species in cancerous tissues compared to those of healthy ones. Furthermore, we show that the characteristic parameters of the microplasma, generated on the unhealthy tissues, are elevated. We report higher decibel audio signals emanating from laser induced microplasma and a subsequent audio blueshift for malignant tissues. The higher abundance of trace elements in cancerous tissues as well as higher plasma temperature and electron density in laser induced microplasma (leading to a stronger shockwave) intensify the acoustic signals.
