“…2014 ). The natural easy biodegradable polymeric materials include proteins (soy, wheat, corn, gluten, whey, collagen, gelatin, and albumin), polysaccharides (chitosan, alginates, starch, cellulose, and chitin), nucleic acids and lipids (bees, wax, and free fatty acids), carbohydrates (pullulan and curdlan), polyhydroxy butyrate (PHB), polyhydroxyalkanoic acids ( Steinbüchel 2005 ; Mathew and Radhakrishnan, 2019 ; Chaudhary et al, 2020 ; Panchal and Vasava, 2022 ) while these slowly biodegradable compounds belong to polyphenols and polyisoprenoids that are represented by lignin and poly (cis-1,4-isoprene), respectively ( Steinbüchel 2005 ).…”

“…The synthetic biodegradable biopolymers include poly (lactic acid) (PLA), poly-(glycolic acid) (PGA), poly (lactic-co-glycolic acid) (PLGA), poly (butylene succinate) (PBA), polycaprolactone (PCL), poly (ethylene adipate) (PEA), poly (p-dioxanone) (PDS), and their copolymers ( Rodrigues and Vieira, 2019 ; Panchal and Vasava, 2022 ). In turn, non-biodegradable synthetic polymers can be categorized into high-density (HDPE) and low-density polyethylene (LDPE) including e.g., ethylene vinyl acetate (EVA), polyethylene terephthalate (PET), polyethylene (PE), polypropylene (PP) and polystyrene (PS) ( Mathew and Radhskrishnan, 2019 ).…”

Natural polymer-based nanocomposites have received significant attention in both scientific and industrial research in recent years. They can help to eliminate the consequences of application of petroleum-derived polymeric materials and related environmental concerns. Such nanocomposites consist of natural biopolymers (e.g., chitosan, starch, cellulose, alginate and many more) derived from plants, microbes and animals that are abundantly available in nature, biodegradable and thus eco-friendly, and can be used for developing nanocomposites for agriculture and food industry applications. Biopolymer-based nanocomposites can act as slow-release nanocarriers for delivering agrochemicals (fertilizers/nutrients) or pesticides to crop plants to increase yields. Similarly, biopolymer-based nanofilms or hydrogels may be used as direct product coating to extend product shelf life or improve seed germination or protection from pathogens and pests. Biopolymers have huge potential in food-packaging. However, their packaging properties, such as mechanical strength or gas, water or microbial barriers can be remarkably improved when combined with nanofillers such as nanoparticles. This article provides an overview of the strategic applications of natural polymer nanocomposites in food and agriculture as nanocarriers of active compounds, polymer-based hydrogels, nanocoatings and nanofilms. However, the risk, challenges, chances, and consumers’ perceptions of nanotechnology applications in agriculture and food production and packaging have been also discussed.

“…12 Unlike branched polymers, synthesis of MSPs is more feasible as the dense shell structures are reduced to form linear arms that can possess a maximum arm length, thus reasonably minimizing the steric hindrance. 13 Fabricating approaches for BPMs based MSPs mainly include: (1) core-first 14 (2) arm-first 15 (3) coupling-onto. 16 In coupling-onto approach, a variety of polymeric arms are synthesized and then coupled with a multifunctional core.…”

A series of seven AB2-type hydrophobic miktoarm star polymeric nanomaterials were nanofabricated using coupling-onto approach. These tridentate nano-stars were synthesized using carbodiimide chemistry and characterized using FT-IR, 1H NMR and DLS techniques. Lactic acid is chosen as “arm A” and amino adipic acid as “core”, while seven biodegradable synthetic amides and polyamides as “arm B” were used individually. The diameter of the smallest nano-star LCE was 558.6 nm and largest nano-star LTD was 733.3 nm. The presence of long aliphatic chain in the LDE and LDD as well as presence of aromatic ring in LTE and LTD give them a bigger diameter in comparison to LCE, LLE and LLD. TGA analysis of the product reported a significant loss of 35% by total mass at 400ᵒC, indicating thermal degradation. The products proved to be biodegradable after 15 days of biological treatment. Biodegradation was structurally confirmed by FT-IR analysis of degraded samples.
