Skin injuries occur when cellular integrity is compromised due to mechanical, physical, or metabolic factors. This study reported on a carboxymethylcellulose (CMC)-based film incorporating TiNT, aiming at its application as a wound dressing. As a minimally invasive approach, titanate nanotubes (TiNT) have been studied due to their photocatalytic properties, biocompatibility, large pore volume, and high surface area. Functionalization with aminosilane groups, using the biological responses of nitrogen, has been explored to enhance cellular interaction. Upon exposure to UV radiation, the dressing releases nanotubes, protecting the lesion from external pathogens and promoting healing. TiNTs were synthesized via a hydrothermal method and 0.2% (v/v) functionalized using 3-aminopropyltrimethoxysilane (APTMS). The films were prepared with 1 (wt%) TiNT or TiNT_NH2 in a 2 (wt%) CMC solution and dried at 60°C for 24 h. Results showed enhanced thermal stability and the potential for controlled nanoparticle release under UV light, with no cytotoxic effects observed. The films demonstrated excellent biocompatibility, making them promising candidates for medical applications.

Metal single atoms have been demonstrated to induce surface-enhanced Raman scattering (SERS) due to their effectiveness in the modification of electronic structure. However, precisely modulating the relative positions of metal single atoms on sub-nanolattices remains a formidable challenge, which makes SERS studies of metal single atoms dependent on localized environments still lacking. Herein, we rely on polyethylene glycol (PEG) as a soft template to achieve the modulation of the relative positions of W atoms on titanate nanotubes (W-TNTs) and probe the local-environment-dependent SERS induced by metal single atoms based on this technique.

In this research, a single composite-type stretchable triboelectric nanogenerator (TENG) is proposed for efficient energy harvesting and handwriting recognition. The composite TENGs were fabricated by blending dielectric barium titanate (BT) and conductive carbon nanotubes (CNTs) in varying amounts into a styrene-butadiene rubber matrix. The energy harvesting efficiency depends on the type and amount of fillers, as well as their dispersion within the matrix.

The triboelectric nanogenerator (TENG) represents a distinctive energy harvesting technology. However, polymer-based TENG faces substantial challenges in retaining stable triboelectric output and structural robustness across temperature extremes and humidity gradients. These limitations stem from inherent material degradation and interfacial charge dissipation under harsh conditions.

Wearable piezoelectric sensors have gained significant attention for real-time biomechanical monitoring applications, yet existing designs often suffer from limited sensitivity, durability, and dynamic response. To address these challenges, we develope a wearable sensor utilizing gradient-architected CNT/PMN-PT/PVDF piezoelectric composites for continuous gait monitoring during weight-bearing walking. The sensor features a dual-filler gradient configuration within a poly(vinylidene fluoride) (PVDF) matrix, in which strategically distributed carbon nanotubes (CNTs) and lead magnesium niobate-lead titanate (PMN-PT) ceramic particles synergistically enhance electromechanical coupling efficiency.
