Nowadays, microalgal research is predominantly centered on an industrial scale. In general, multipotent bioactive peptides are the advantages over focal points over utilitarian nourishment as well as nutraceuticals. Microalgal peptides are now profoundly connected with biological properties rather than nutritive. Numerous techniques are employed to purify active peptides from algal protein using enzymatic hydrolysis; it is broadly used for numerous favorable circumstances. There is a chance to utilize microalgal peptides for human well-being as nutritive enhancements. This exhaustive survey details the utilization of microalgal peptides as antioxidant, anti-cancerous, anti-hypersensitive, anti-atherosclerotic, and nutritional functional foods. It is also exploring the novel technologies for the production of active peptides, for instance, the use of algal peptides as food for human health discovered restrictions, where peptides are sensitive to hydrolysis protease degradation. This review emphasizes the issue of active peptides in gastrointestinal transit, which has to be solved in the future, and prompt impacts.

Palladium (Pd) exhibits excellent catalytic properties and is involved in organic synthesis, mitigation of pollutants, and so on. However, it is less explored in biomedical applications. The utilization of palladium nanoparticles (PdNPs) possesses a large surface area, allowing them to adsorb significant amounts of ligands. In this study, PdNPs were prepared by mixing various concentrations of Pd nitrate with hydroxypropyl methyl cellulose (HPMC) at concentrations of 1% and 3%. The resulting solution was treated with a solution plasma process (SPP) using a unipolar supply, with a minimum discharge time of approximately 30–60 s. Pd rods were used as electrodes to avoid contamination in the biocomposites. The formation of HPMC/PdNPs nanobiocomposites was confirmed by the color change of the brown color solution turned from dark brown (at 30 s) to black color (at 60 s) and was confirmed by ultraviolet–visible (UV–Vis) spectroscopy. Following that, a nanobiocomposites scaffold was fabricated and cross-linked using lyophilization. The analysis of the nanobiocomposites showed a fibril-like structure at the edges which might help to bind with cells. The synthesized nanoparticles exhibited a stable spherical shape with an average size of 2–8 nm. These nanoparticles were embedded within the cellulose matrix, resulting in a composite material with potential applications in various fields. The in vitro studies from HPMC/PdNPs nanocomposites were investigated with HeLa cells for cytotoxic studies.
