Skin is the largest protective organ that could be recurrently wounded and attacked by microorganisms. The skin safeguarding supporting were intended through natural derivatives. Fish collagen (Cg) type I, extracted from sea bream (Spondyliosoma cantharus), chitosan nanoparticles (NCht) shrimp shells, henna (Lawsonia inermis L.) leaves extract (He) produced physiochemically characterized. antim...

Chitosan (CS)-g-poly (acrylic acid) (PAA) nanoparticles, which are well dispersed and stable in aqueous solution have been prepared by template polymerization of acrylic acid in chitosan solution. The prepared CS-PAA had a white powder shape and was insoluble in water and diluted acid. The mean particles size were found to be around 50nm. FTIR spectra of CS-PAA nanoparticles for CS, the intensi...
