AI Technical Summary

Technical Problem

Existing methods for preparing nano-starch suspensions are limited by their suitability for intended uses, often requiring acidic or alkaline environments, surfactants, and generating wastewater, which degrade the utility of nano-starch particles and limit their stability, especially under basic conditions.

Method used

A novel preparation method for nano-starch and nano-starch/ester suspensions that are aqueous-based, avoiding acidic or alkaline hydrolysis, surfactants, and wastewater generation, and utilizing fewer steps to create stable nano-starch suspensions that can be iodinated for improved stability and mechanical properties.

Benefits of technology

The method produces nano-starch suspensions with enhanced stability, particularly under basic conditions, allowing for longer-term molecular iodine stability and improved mechanical properties, suitable for applications such as wound healing and bone void fillers.

Abstract

Novel methods of preparing nano-starch or nano-starch / ester suspensions are disclosed in this application. The obtained nano-starch suspensions and nano-starch / ester suspensions showed unexpectedly high stabilities and can be iodinated using various iodine solutions to provide iodinated nano-starch suspensions and nano-starch / ester suspensions that have long-term stabilities and improved stabilities under basic conditions. New products can be prepared using the nano-starch suspensions, nano-starch / ester suspensions, iodinated nano-starch suspensions, and / or nano-starch / ester suspensions and used for applications as disclosed herein.
