“…This leads to increase in surface tension, membrane permeability, change in membrane texture, morphology, and generation of oxidative stress, which result in bacterial cell death . ZnO nanoparticles (≤10 nm) passage through the cytoplasm membrane and accumulate inside bacterial cells (via particle internalization), which damages the intercellular constituents, including nucleic acids, etc. , …”

The majority of failures in prosthetic implants and devices are caused by infections. Microbial infections are one of the major causes of these failures. The present article reviews various techniques such as modification in surface chemistry/composition and tailored structures (micro to nano) for improving the antibacterial response of prosthetic implants. In addition, the application of external stimulants such as magnetic and electric fields, as well as polarization, is recently realized as a fairly appealing approach to diminish the bacterial population. A comprehensive response of surface modifications as well as external stimuli in inducing the antibacterial response in prosthetic implants has also been summarized. The mechanisms for the antibacterial response due to these modifications, such as generation of toxic metal ions by dissolution of their respective oxides, and production of reactive oxygen species (ROS), such as singlet oxygen, hydroxyl radicals (OH–), hydrogen peroxide (H2O2), superoxides, peroxides (O2 –2), etc., have been elaborately discussed.

“…It is assigned to the Zn-O stretching vibration which confirms the nanocrystalline structure of the grown ZnO NRs [ 31 , 40 , 41 ]. The peak observed at around 1605 cm −1 relates to the stretching mode of C-O and C=O [ 42 ]. The peak observed at 1366 cm −1 corresponds to the CH bending vibration in cellulose [ 43 ].…”

Cellulose is the most abundant organic material on our planet which has a key role in our daily life (e.g., paper, packaging). In recent years, the need for replacing fossil-based materials has expanded the application of cellulose and cellulose derivatives including into electronics and sensing. The combination of nanostructures with cellulose nanofibers (CNFs) is expected to create new opportunities for the development of innovative electronic devices. In this paper, we report on a single-step process for the low temperature (<100 °C), environmentally friendly, and fully scalable CNF-templated highly dense growth of zinc oxide (ZnO) nanorods (NRs). More specifically, the effect of the degree of substitution of the CNF (enzymatic CNFs and carboxymethylated CNFs with two different substitution levels) on the ZnO growth and the application of the developed ZnO NRs/CNF nanocomposites in the development of UV sensors is reported herein. The results of this investigation show that the growth and nature of ZnO NRs are strongly dependent on the charge of the CNFs; high charge promotes nanorod growth whereas with low charge, ZnO isotropic microstructures are created that are not attached to the CNFs. Devices manufactured via screen printing/drop-casting of the ZnO NRs/CNF nanocomposites demonstrate a good photo-sensing response with a very stable UV-induced photocurrent of 25.84 µA. This also exhibits excellent long-term stability with fast ON/OFF switching performance under the irradiance of a UV lamp (15 W).
