Biosoluble surgical material from 2,3-dialdehyde cellulose.
Dialdehyde cellulose (DAC) was prepared by periodate oxidation of various cellulosic materials in the form of sutures and bandages. The suitability of using DAC for making bioabsorbable sutures and antimicrobial wound dressing bandages was studied. The investigations indicated that DAC combines the requisite mechanical strength with an inherent antimicrobial nature. It was found that the oxidation of cellulose to yield DAC also rendered it bioabsorbable. The DAC was coated with different concentrations of urea formaldehyde in order to improve the mechanical properties for making sutures.
