Nowadays, carbon nanotubes (CNTs) due to their inorganic conducting, semiconducting, and organic π-π stacking properties are becoming innovative materials. CNTs have an adjustable size, large surface area, and other significant chemical properties. Due to their excellent electrical, optical, and mechanical properties, CNTs play an important role in various application fields. In the past decade, many unique intrinsic physical and chemical properties have been intensively explored for pharmaceutical, biological, and biomedical applications. The functionalization of CNTs results in a remarkably reduced cytotoxicity and at the same time increased biocompatibility. The toxicity studies reveal that highly water-soluble and serum stable nanotubes are biocompatible, nontoxic, and potentially useful for biomedical applications. Ultrasensitive drug determination from its dosage form and/or biological samples with carbon nanotubes can be realized after surface modification. The main purpose of this review is to present recent achievements on CNTs which are investigated in electrochemical and chromatographically sensing technologies.

Unwanted icing on solid surfaces presents a critical challenge in a wide range of technological applications due to its detrimental effects on functional stability, energy efficiency, and overall system reliability. To address this phenomenon, multiple strategies have been explored, including the development of icephobic surface coatings, mechanical deicing techniques, thermal deicing systems, deployment of chemical deicing agents, and other advanced mitigation methods. In this study, novel nano-magnetically functionalized polyvinylidene fluoride (PVDF)/Fe₃O₄ fibrous films were engineered, exhibiting enhanced potential for use as icephobic materials. The electrospinning process was employed to fabricate highly aligned ferromagnetic nanofibers, with the incorporation of magnetite (Fe₃O₄) nanoparticles into the PVDF matrix leading to a significant increase in the electroactive β-phase fraction. The application of a directional magnetic field during electrospinning facilitated the production of uniformly oriented nanofiber architectures, enabling comprehensive evaluation of their morphological characteristics and anti-icing performance. Advanced characterization techniques, including wettability and icephobicity assessments, infrared spectroscopy, Fourier-transform infrared (FTIR) spectroscopy, atomic force microscopy (AFM), and scanning electron microscopy (SEM), were employed. The findings demonstrate that the precisely oriented nano-fibrous magnetic coatings exhibit superior icephobic performance, underscoring their suitability for next-generation anti-icing and deicing applications in critical technological systems.
