Agricultural and Biomedical Applications of Chitosan-Based Nanomaterials

Abstract

Chitosan has emerged as a biodegradable, nontoxic polymer with multiple beneficial applications in the agricultural and biomedical sectors. As nanotechnology has evolved as a promising field, researchers have incorporated chitosan-based nanomaterials in a variety of products to enhance their efficacy and biocompatibility. Moreover, due to its inherent antimicrobial and chelating properties, and the availability of modifiable functional groups, chitosan nanoparticles were also directly used in a variety of applications. In this review, the use of chitosan-based nanomaterials in agricultural and biomedical fields related to the management of abiotic stress in plants, water availability for crops, controlling foodborne pathogens, and cancer photothermal therapy is discussed, with some insights into the possible mechanisms of action. Additionally, the toxicity arising from the accumulation of these nanomaterials in biological systems and future research avenues that had gained limited attention from the scientific community are discussed here. Overall, chitosan-based nanomaterials show promising characteristics for sustainable agricultural practices and effective healthcare in an eco-friendly manner.

Evaluation of Antinociceptive Effects of Chitosan-Coated Liposomes Entrapping the Selective Kappa Opioid Receptor Agonist U50,488 in Mice

“…Due to its low toxicity, biodegradability and biocompatibility, chitosan has been increasingly studied in a wide range of pharmaceutical, biomedical, and biotechnological fields, including gene therapy, bone regeneration, food industry, and agriculture [ 45 , 46 ]. Chitosan displays hemostatic and hastening wound healing effects, anti-hypercholesterolemic effects, bioactivity, chemotactic actions, antimicrobial activity, immunostimulation, enzymatic biodegradability, mucoadhesion, andepithelial permeability [ 47 , 48 , 49 , 50 ].…”

“…For obtaining chitosan-based nanoparticles, several methods have been described: polyelectrolyte complexation, emulsion-droplet coalescence, emulsion crosslinking, ionotropic gelation, reverse micellization, and precipitation [ 48 , 51 ].…”

The Inhibitory Concentration of Natural Food Preservatives May Be Biased by the Determination Methods

“…It is obtained by deacetylation of chitin [ 14 ], a structural polysaccharide derived from the exoskeleton of crustaceans, insects, and the cell wall of fungi [ 9 ]. This compound can inhibit the growth of fungi and bacteria [ 15 ] and can be used in food, biomedical, and agricultural industries [ 16 ]. Propolis is a natural product composed of various amounts of resins and beeswax collected by honeybees [ 9 ].…”

Электростимуляция Дермальных Фибробластов Человека На Электропроводящей Матрице

“…Это полисахарид, получаемый из биомассы: панцирей креветок, крабов, саранчи и т. д. Среди биосовместимых полимеров, по масштабам производства и по доступности, хитозан занимает второе место после производных целлюлозы [10]. Хитозан не только биосовместимый, но и биодеградируемый полимер и обладает также бактерицидными свойствами [11]. Пленки на основе хитозана, сочетающие превосходные механические и антибактериальные свойства, используют для упаковки скоропортящихся продуктов [12], полимер применяют для антибактериальной очистки питьевой воды [13] и выведения из организма продуктов разложения лекарственных препаратов [14,15].…”
