    "content": "The monomers used for synthesizing hydrophilic polymers include naturally occurring polymers like alginate, chitosan, dextran, and hyaluronic acid, as well as synthetic polymers such as poly(N-isopropylacrylamide) (PNIPAM) and poly(oligo ethylene glycol methacrylate) (POEGMA), where functional groups such as hydrazide, aldehyde, charged moieties, and ethylene oxide (EO) repeat units enhance the hydrophilicity by enabling better interaction with water through hydrogen bonding, electrostatic interactions, and the ability to undergo swelling and deswelling in response to environmental changes like temperature and pH.Monomers used for synthesizing hydrophilic polymers include oligo(ethylene glycol) methyl ether methacrylate (OEGMA), di(ethylene glycol) methyl ether methacrylate (M(EO)2MA), acrylic acid (AA), thioglycolic acid (TGA), and N,N-dimethylaminoethyl methacrylate (DMAEMA), with functional groups such as hydroxyl (-OH), carboxylic acid (-COOH), and amine (-NH2) enhancing the hydrophilicity of the polymers, as these polar functional groups increase hydrogen bonding and ionic interactions with water molecules, thereby promoting better affinity and solubility in aqueous environments."
