Dear friends, of the weakening of ... Gender, 🦞

I hope in the #future, gender will be more fluid. With everyone able to move throughout #life between #safe hormones and #advances in #medicine. Just as I hope advances in #alternative #parenting #options will make more #acceptable #diverse options available. :QueerCat_Trans:

I probably won't live to be #spare-part #third-hand #cyborg. One can but dream ... :blobcatsleep:

Of course, we can #plan and #experiment now, in some places and #situations more than others. 🏴

MDPIRecent Advances in Chitosan-Based Applications—A ReviewChitosan derived from chitin has gathered much interest as a biopolymer due to its known and possible broad applications. Chitin is a nitrogen-enriched polymer abundantly present in the exoskeletons of arthropods, cell walls of fungi, green algae, and microorganisms, radulae and beaks of molluscs and cephalopods, etc. Chitosan is a promising candidate for a wide variety of applications due to its macromolecular structure and its unique biological and physiological properties, including solubility, biocompatibility, biodegradability, and reactivity. Chitosan and its derivatives have been known to be applicable in medicine, pharmaceuticals, food, cosmetics, agriculture, the textile and paper industries, the energy industry, and industrial sustainability. More specifically, their use in drug delivery, dentistry, ophthalmology, wound dressing, cell encapsulation, bioimaging, tissue engineering, food packaging, gelling and coating, food additives and preservatives, active biopolymeric nanofilms, nutraceuticals, skin and hair care, preventing abiotic stress in flora, increasing water availability in plants, controlled release fertilizers, dye-sensitised solar cells, wastewater and sludge treatment, and metal extraction. The merits and demerits associated with the use of chitosan derivatives in the above applications are elucidated, and finally, the key challenges and future perspectives are discussed in detail.
