“…The soluble starch is extracted and heated, so it becomes humidity-resistant which results in smooth hair and skin. So, it is mostly used as an ingredient in skin lotion and hair care products [ 229 ]. Chitosan is used in lotion and nail lacquers which is a good moisturizing agent and used to moisturize the lips and skin [ 230 ].…”

Biodegradable polymers have emerged as fascinating materials due to their non-toxicity, environmentally benign nature and good mechanical strength. The toxic effects of non-biodegradable plastics paved way for the development of sustainable and biodegradable polymers. The engineering of biodegradable polymers employing various strategies like radical ring opening polymerization, enzymatic ring opening polymerization, anionic ring opening polymerization, photo-initiated radical polymerization, chemoenzymatic method, enzymatic polymerization, ring opening polymerization and coordinative ring opening polymerization have been discussed in this review. The application of biodegradable polymeric nanoparticles in the biomedical field and cosmetic industry is considered to be an emerging field of interest. However, this review mainly highlights the applications of selected biodegradable polymers like polylactic acid, poly( ε -caprolactone), polyethylene glycol, polyhydroxyalkanoates, poly(lactide-co-glycolide) and polytrimethyl carbonate in various fields like agriculture, biomedical, biosensing, food packaging, automobiles, wastewater treatment, textile and hygiene, cosmetics and electronic devices.

“…These data help to create smart food. On the other hand, many of the biomass-derived materials are highly recommended for the fabrication of electro-analytical tools due to their unique features such as sustainability, regenerative nature, and cost-effectiveness [4]. Therefore, sensors and especially electrochemical sensors are a new approach in analytical systems to achieve sustainability goals.…”

A high performance and fast response sensor was fabricated as a monitoring system for the determination of butylated hydroxyanisole (BHA) in food and wastewater samples. In this regard, a carbon paste electrode (CPE) that was amplified with platinum-decorated single wall carbon nanotubes (Pt/SWCNTs) and 1-Butyl-3-methylimidazolium chloride ([C4mim][Cl]) was investigated as a new electroanalytical sensor for the monitoring of BHA in aqueous solution. The [C4mim][Cl]/Pt/SWCNTs/CPE offered an excellent catalytic activity on oxidation signal of BHA and enhanced its oxidation current about 5.51 times. In the final step, the standard addition results confirmed the powerful ability of [C4mim][Cl]/Pt/SWCNTs/CPE to the monitoring of BHA in different water and food samples with acceptable recovery data.

“…The preparation of GO using the Hummers method requires not only a strong acid and an oxidant but also generates large quantities of waste liquids. ,, In addition, the methods need to rely on precursors from fossil fuel, which are not only harmful to the environment but also expensive. , In contrast, BCMs are not only more abundant in raw materials but also relatively environmentally friendly in the preparation process . Therefore, in recent years, BCMs have attracted increasing attention in the fields of energy storage, oil/water separation, and fluorescent sensors …”

Sycamore villus fibers were used to prepare hollow and porous carbon microtubes (CMTs) and the ZnO/CMT composite with heterojunctions by simple carbonization for the first time. Because the hollow and porous structure provided more channels to facilitate the adsorption and desorption of gas molecules, both CMTs and ZnO/CMT exhibited higher sensitivity and quicker response (<16 s) to and recovery (<2 s) from multiple target analytes. Furthermore, ZnO nanoparticles were uniformly dispersed on the CMTs by zinc acetate-assisted carbonization, which avoided the agglomeration of ZnO and formed a large number of heterojunctions, greatly improving the sensitivity of ZnO/CMT. In comparison to the pure CMTs and ZnO, the response of ZnO/CMT to the four target gases increased by 1.4∼4.3 and 9.9∼18.1 times, respectively. Their limit of detection for NH 3 was calculated as 62.5 and 8.8 ppb, respectively. After 30 days, the responses of CMTs and ZnO/CMTs to 500 ppm NH 3 decreased by 9.4 and 6.5%, respectively. This indicated that CMTs and ZnO/CMT had high sensitivity and good long-term stability. This study provides a feasible way for the gas-sensing application of biomass carbon materials with heterojunction structures.
