Preparation and characterisation of new biomaterials based on chitosan iodide with biologically active dyes
New composite materials were obtained based on chitosan iodide and
organic dyes – methylene blue and fuchsine in fucorcin (Castellani liquid) –
by using a simple synthetic procedure. The materials were characterised by
scanning electron microscopy, X-ray diffraction, temperature-programmed
desorption mass spectrometry, infrared spectroscopy and visible and
ultraviolet light spectroscopy. The dyes in the composites were distributed
uniformly and did not form separate phases. These composites could form
structured porous sponges and films and therefore be used in various
fields of application. The materials displayed antibacterial activity against
antibiotic resistant gram-positive and gram-negative bacteria
