Lire la suite >Chitosan (CS) presents antibacterial, mucoadhesive and hemostatic properties and is an ideal candidate for wound dressing applications. This work reports the development of sponge-like materials obtained from physical hydrogels after the interaction between CS and a β-cyclodextrin polymer (PCD) in acidic conditions to provoke immediate gelation. Characterization consisted of zeta potential (ZP) measurements, rheology analysis, Fourier transform infrared (FTIR), Raman spectroscopy, wide angle X-ray scattering (WAXS) and scanning electron microscopy (SEM). Swelling behavior, cytotoxicity, drug sorption and drug delivery properties of sponges were assessed. ZP indicated that CS and PCD presented opposite charges needed for physical crosslinking. Rheology, swelling, and cytotoxicity of sponges depended on their CS:PCD weight ratios. Increasing PCD in the mixture delayed the gel time, reduced the swelling and increased the cytotoxicity. FTIR and Raman confirmed the physical crosslinking between CS and PCD through ionic interactions, and WAXS showed the amorphous state of the sponges. Finally, the efficiency of chlorhexidine loaded sponge against S. aureus bacteria was proved for up to 30days in agar diffusion tests.Lire moins >
