Preparation and characterisation of new bioactive polysaccharides based on grafted starch

Abstract

PurposeThe preparation and characterisation of new bioactive polymeric materials.Design/methodology/approachNew bioactive polysaccharide were prepared by grafting of acrylonitrile onto water soluble starch and then reacting with bioactive heterocyclic rings. The biological activity, against bacteria, of the materials prepared was studied.FindingsSome of the prepared bioactive materials show high disinfecting power against bacteria.Research limitations/implicationsThe bioactive materials were prepared by grafting acrylonitrile onto starch and then reacting the resulting material with cyanuric acid and 2‐aminothiazole. Many other heterocyclic rings that contain tertiary nitrogen atom or amide nitrogen can also be used.Practical implicationsThe new bioactive materials prepared can be used for disinfecting purposes.Originality/valueSome of the materials prepared were used successfully in killing bacteria, as such, can be used as disinfecting materials.
