Carbon-based nanoparticles (CNPs) have gained recognition because of their good biocompatibility, easy preparation, and excellent phototherapy properties. In biomedicine applications, CNPs are widely applied as photodynamic agents for antibacterial purposes. Photodynamic therapy has been considered a candidate its noninvasiveness minimal side effects, especially in the improvement activity against multidrug-resistant bacteria, compared with conventional antibiotic medicines. Here, we...
This study develops SnO2-based gas sensors integrated with a low-temperature co-fired ceramic (LTCC) micro hotplate for ethanol detection. SnO2 nanoparticles were synthesized using simple precipitation method, and sensing layers varying thicknesses around 0.24 µm, 0.71 1.20 µm applied to evaluate their influence on performance. The results show that the optimal configuration is layer, offering high sensitivity, fast response, efficient recovery. Operating at low voltage of 3.2 V, exhibit...
Higher-ordered 3D macroporous TiO2-functionalized chitosan scaffolds were prepared by ice segregation induced self-assembly (ISISA), in which homogenous dispersions of 6, 27 or 200 nm sized TiO2nanoparticles and cross-linked with glycidoxypropyltrimethoxysilane unidirectionally frozen at −196 °C. Scanning electron microscopy showed that under established optimum conditions the monoliths comprised well-aligned 30–50 µm micro-channels running parallel to direction growth. The surface...
Most perovskite publications explore only one or two formulas to achieve good performance and/or stability. In contrary, this work aims provide fair comparisons among different popularized recipes (MAPbI3, FAPbI3, FA0.1MA0.9PbI3, Cs0.2FA0.8PbI2.25Br0.75, Cs0.05FA0.81MA0.14PbI2.55Br0.45, and (PEA)2MA39Pb40I121) on the basis of mechanical electrical properties together with deformation stability via force curve analysis, photoconductive atomic microscopy (c-AFM), Kelvin probe (KPFM), Raman...
Reactive oxygen species (ROS) play a role in multiple physiological processes. In contrast, an excessive generation of ROS can harm various biological components, including proteins, lipids, and DNA, leading to accelerated aging, illness, inflammatory disorders. Carbon-based nanomaterials (CNMs) are well-known widely developed for antioxidant activity because their great biocompatibility, low toxicity, easy synthesis, unique physicochemical properties, especially scavenging ability. The most...
