Novel antiviral activity of dialdehyde starch
A significant effort worldwide is being directed toward development of novel biocides against drug-resistant bacterial and viruses because of the significant potential human infection risks in the general population. We report here the discovery of a strong antiviral biocide, dialdheyde starch (DAS). Antiviral tests were carried out against three non-envelop viruses, including two bacterial vir...
متن کاملN-succinyl chitosan–dialdehyde starch hybrid hydrogels for biomedical applications
A new class of injectable, biocompatible and biodegradable hydrogel is reported. This hydrogel is derived from N-succinyl chitosan (SCS) mixed with water-soluble dialdehyde starch (DAS) without using a conventional chemical crosslinker. The hybrid hydrogel is formed owing to the Schiff's base reaction between amine groups of SCS and dialdehyde groups of DAS to form -CH 000000000000 000000000000...
متن کاملOptimization of the electrospinning process of polyurethane nanofibers and their filtration performance for use in respiratory protection mask filters
Background and Aim: Electrospun nanofibers can be used to produce filter media in personal protective equipment for the military. The present study aimed to optimize the electrospinning process used to create polyurethane nanofiber substrates and compare the optimum substrate filtration performance with a typical commercial substrate used in the structure of N95 respirators. Methods: In this ex...
متن کاملBacterial Inactivation Kinetics of Dialdehyde Starch Aqueous Suspension
The bacterial inactivation kinetics of dialdehyde starch (DAS) aqueous suspension was studied by the relationship between the minimal lethal concentration (MLC) and the inactivation time at four different temperatures. The relationship between MLC and exposure time was found to follow the first-order Chick-Watson law. This first-order inactivation kinetics was modeled by pseudo-first order chem...
