“…Many scientists have focused on starches, which are the most abundant, inexpensive, and easily accessible of these natural materials. Corn, wheat, and rice are the most common sources of starch, which are available in the forms of amylose and amylopectin . Amylose is available at levels up to 25% contingent on the source with a low molecular weight that varies between 10,000 and 60,000 g mol –1 .…”

Nb/starch-doped ZnO quantum dots (QDs) were prepared by a coprecipitation route. A fixed quantity of starch (st) and different concentrations (2 and 4%) of niobium (Nb) were doped in a ZnO lattice. To gain a better understanding of synthesized nanostructures, a systematic study was carried out utilizing several characterization methods. The goal of this research was to undertake methylene blue (MB) dye degradation with a synthetic material and also study its antibacterial properties. The phase structure, morphology, functional groups, optical properties, and elemental compositions of synthesized samples were investigated. Our study showed that ZnO QDs enhanced photocatalytic activity (PCA), resulting in effective MB degradation, in addition to showing good antimicrobial activity against Gram-negative relative to Gram-positive bacteria. Molecular docking study findings were in good agreement with the observed in vitro bactericidal potential and suggested ZnO, st-ZnO, and Nb/st-ZnO as possible inhibitors against dihydrofolate reductase (DHFRE. coli) and DNA gyraseE. coli.

“…Through grafting various monomers onto starch, biodegradable polymers have been created. Ammonium persulphate has been utilized as an initiator for the formation of free radicals in free radical polymerization procedures (Iqbal et al, 2021; Iqbal et al, 2021). The process for making nickel nanoparticles was previously described.…”

Grafting of starch with methyl methacrylate was carried out using a free radical mechanism. Free radicals were generated by the thermal disintegration of potassium persulphate at the temperature of 60 C. A variety of experimental methods were investigated to check the effect of different parameters such as (temperature, amount of starch, quantity of monomer) for efficient grafting. The optimum temperature found for good grafting was 60 C. The initial amount of starch was taken as 0.75 g. Keeping the amount of starch constant, the quantity of monomer was reduced gradually from 10 to 2 ml in portions of 5 and 3 ml. The controlled biodegradability of the grafted product was obtained by using a 3 ml monomer in 0.75 g starch. This grafted polymer showed 31.45% biodegradability in 60 days. The nanocomposite of starch grafted methyl methacrylate was prepared by incorporating 0.02 g Ni nanoparticles in the reaction flask 15 min before the completion of reaction time. The starch grafted polymer and nanocomposite of this were fully characterized by SEM, FTIR, TGA, and DSC techniques. The soil burial method was applied to estimate the biodegradability of samples. The polymer containing Ni nanoparticles was less biodegradable than without nanoparticles. Such polymers can be efficiently used as packaging material for food items. Research Highlights1. Through a free radical method, methyl methacrylate was grafted onto the backbone of starch in this study.2. During the process, nickel nanoparticles were added to achieve the nickel nanocomposite of the starch grafted polymer.3. The breakdown of starch grafted polymer after 60 days in a soil burial experiment was 31.45%, whereas the degradation of nanocomposites was 20.07%. 4. Our synthesized nanocomposite polymers can be effectively employed as packaging material for food items.
