The field of nanotechnology is concerned with the creation and application of materials having a nanoscale spatial dimensioning. Having a considerable surface area to volume ratio, nanoparticles have particularly unique properties. Several chemical and physical strategies have been used to prepare zinc oxide nanoparticles (ZnO-NPs). Still, biological methods using green or natural routes in various underlying substances (e.g., plant extracts, enzymes, and microorganisms) can be more environmentally friendly and cost-effective than chemical and/or physical methods in the long run. ZnO-NPs are now being studied as antibacterial agents in nanoscale and microscale formulations. The purpose of this study is to analyze the prevalent traditional method of generating ZnO-NPs, as well as its harmful side effects, and how it might be addressed utilizing an eco-friendly green approach. The study’s primary focus is on the potential biomedical applications of green synthesized ZnO-NPs. Biocompatibility and biomedical qualities have been improved in green-synthesized ZnO-NPs over their traditionally produced counterparts, making them excellent antibacterial and cancer-fighting drugs. Additionally, these ZnO-NPs are beneficial when combined with the healing processes of wounds and biosensing components to trace small portions of biomarkers linked with various disorders. It has also been discovered that ZnO-NPs can distribute and sense drugs. Green-synthesized ZnO-NPs are compared to traditionally synthesized ones in this review, which shows that they have outstanding potential as a potent biological agent, as well as related hazardous properties.

The objective of the study is the chemical synthesis of ZnO powders, from ZnCl2 and NaOH solutions according to an appropriate procedure. The powders (a) and (b) obtained underwent various characterizations such as: optical microscopy, SEM, UV, BET, IR, XRD and antimicrobial activity. The results showed the inhomogeneous distribution, the nanometric size, the absorbance at 353 and 346 nm and the specific surface of 25.701 and 30.534 cm2/g of the particles, the presence of all the characteristic bands of ZnO which was confirmed by XRD and very good bacterial sensitivity of the two ZnO powders.

The theory of high entropy‐dissipative structure is confined to high‐entropy alloys and their oxide materials under harsh conditions, but it is very difficult to obtain high entropy‐dissipative structure for smart sensors based on polymers and metal oxides under mild conditions. Moreover, multiple signal coupling effect heavily hinder the sensor applications, and current multimodal integrated devices can solve two signal‐decoupling, but need very complicated process way. In this work, new synthesis concept is the first time to fabricate high entropy‐dissipative conductive layer of smart sensors with triple‐signal response and self‐decoupling ability within poly‐pyrrole/zinc oxide (PPy/ZnO) system. The sensor (SPZ20) amplifies pressure (17.54%/kPa) and gas (0.37%/ppm), reduces humidity (0.41%/% RH) and temperature (0.12%/°C) signals, simultaneously achieving the triple self‐decoupling effect of pressure and gas in the complex temperature‐humidity field because of the enlarged pressure‐contact area, enhanced gas‐responsive sites, altered vapor path and its own heat insulation function. Additionally, it inherits the strong robustness (500 rubbing, washing, and heating or freezing cycles) and endurance (10 000 photo‐purification cycles) of traditional high‐entropy materials for information transmission and smart alarms in emergencies or harsh environments. This work gives a new insight into the multiple‐signal response and smart flexible electronic design from natural fibers.
