“…Chitosan is an environmentally and eco-friendly polymer with multipurpose applications in various fields such as agriculture, cosmetology, food, paper, pharmacy and textile industries [64][65][66][67][68] and a potent agent for the removal of toxic pollutants [69,70]. It can be used in plant production systems as a single compound or combined with other polymers and elements [68,71]. It is considered one of the most abundant natural biopolymers.…”

“…Moreover, the application of nanochitosan solutions via soaking of seedlings or foliar spraying showed better results in terms of onion crop performance and nutrient use efficiency [113]. The advanced techniques in nanoparticle preparation have allowed the efficient capitalization of chitosan's beneficial effects not only in agriculture but also in the food industry through functional packaging [67,68,114]. The use of bio-nanomaterials may also find uses in smart genetic engineering in plants through the editing of plant genomes [71].…”

Chitin and chitosan are natural compounds that are biodegradable and nontoxic and have gained noticeable attention due to their effective contribution to increased yield and agro-environmental sustainability. Several effects have been reported for chitosan application in plants. Particularly, it can be used in plant defense systems against biological and environmental stress conditions and as a plant growth promoter—it can increase stomatal conductance and reduce transpiration or be applied as a coating material in seeds. Moreover, it can be effective in promoting chitinolytic microorganisms and prolonging storage life through post-harvest treatments, or benefit nutrient delivery to plants since it may prevent leaching and improve slow release of nutrients in fertilizers. Finally, it can remediate polluted soils through the removal of cationic and anionic heavy metals and the improvement of soil properties. On the other hand, chitin also has many beneficial effects such as plant growth promotion, improved plant nutrition and ability to modulate and improve plants’ resistance to abiotic and biotic stressors. The present review presents a literature overview regarding the effects of chitin, chitosan and derivatives on horticultural crops, highlighting their important role in modern sustainable crop production; the main limitations as well as the future prospects of applications of this particular biostimulant category are also presented.

“…Whiskers have recently been prepared from Ch from different sources, such as crab, shrimp, and lobster shells and squid pens [ 44 , 45 ]. Morin and Dufresne [ 46 ] prepared nanochitin whiskers from Riftia (marine invertebrates). In another study, Gopalan and Dufresne obtained nanochitin whiskers from crab shells.…”

Chitin/chitosan research is an expanding field with wide scope within polymer research. This topic is highly inviting as chitin/chitosan’s are natural biopolymers that can be recovered from food waste and hold high potentials for medical applications. This review gives a brief overview of the chitin/chitosan based nanomaterials, their preparation methods and their biomedical applications. Chitin nanofibers and Chitosan nanofibers have been reviewed, their fabrication methods presented and their biomedical applications summarized. The chitin/chitosan based nanocomposites have also been discussed. Chitin and chitosan nanofibers and their binary and ternary composites are represented by scattered superficial reports. Delving deep into synergistic approaches, bringing up novel chitin/chitosan nanocomposites, could help diligently deliver medical expectations. This review highlights such lacunae and further lapses in chitin related inputs towards medical applications. The grey areas and future outlook for aligning chitin/chitosan nanofiber research are outlined as research directions for the future.

“…The NCht was comprehensively reported to exhibit powerful antimicrobial actions for fighting microbial pathogens; the main action resulted from NCht surface charges (positive), which enable its attachment to microbial surfaces, deform them, and interfere their permeability [24,25,59]. The nanosized NCht particles could also penetrate into microbial cells and interact with their functional components (e.g., polymerization enzymes, DNA, RNAs, proteins, and enzymes) to inactivate them and prohibit well-organized cell membrane synthesis [24,60,61]. The He contains numerous bioactive constituents that have elevated antimicrobial and cytotoxicity properties against microbial cells, e.g., 1,4-naphthoquinone analogues, lawsone, esculetin, isoplumbagin, hennadiol, laxanthone, lupeol, lacoumarin, fraxetin, betulinic acid, scopoletin, betulin, and flavone glycosides [27,55,56,62]; most of these compounds have diverse microbicidal actions affected the synthesis and development of cells' vital and structural organelles.…”

Skin is the largest protective organ that could be recurrently wounded and attacked by microorganisms. The wounded skin safeguarding and supporting were intended through natural derivatives. Fish collagen (Cg) type I, extracted from sea bream (Spondyliosoma cantharus), chitosan nanoparticles (NCht) from shrimp shells, and henna (Lawsonia inermis L.) leaves extract (He) were produced and physiochemically characterized. The antimicrobial potentialities of these compounds and their composites were assessed toward skin pathogens (Candida albicans and Staphylococcus aureus) using various assaying methods and microimaging techniques. The infrared and electrophoretic analysis of Cg validated its characteristics, and the IR-spectroscopic analysis of the compounds/composites indicated their physiochemical attributes and interrelations. The produced NCht particles had a diameter range of 64.6-308.8 nm, 104 nm mean diameter, and +31.3 mV zeta potentiality. Both NCht, He, and NCht/He composite exhibited significant antimicrobial potentiality toward skin pathogens; NCht/He was the strongest with inhibitory concentrations of 20.0 and 22.5 μg/mL and inhibition zones of 25.7 and 26.8 mm against S. aureus and C. albicans, respectively. The electron micrographs verified the synergistic microbicidal action of NCht/He, as they led to severe microbial lysis and deformations. The skin wounds’ treatment with NCht/He/Cg composite promoted the fastest and complete healing of wounded rats’ skin during 8 days of local treatment, with the absence of inflammation and infection signs; treated with NCht/He/Cg composite, the wound area vastly reduced from 63.6 mm2 to 15.9 and 9.1 mm2 after 2 and 4 days, respectively. The natural NCht/He/Cg composites are recommended as topical applications for optimum skin disinfection and regeneration.
