Preparation and characterisation of new bioactive polysaccharides based on grafted starch

Abstract

Purpose

The preparation and characterisation of new bioactive polymeric materials.

Design/methodology/approach

New 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.

Findings

Some of the prepared bioactive materials show high disinfecting power against bacteria.

Research limitations/implications

The 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 implications

The new bioactive materials prepared can be used for disinfecting purposes.

Originality/value

Some of the materials prepared were used successfully in killing bacteria, as such, can be used as disinfecting materials.
