We have developed an encapsulation platform named RS-BET. It has a broad spectrum of application in the field of oral “drug” delivery system especially for the acid-sensitive drug and the drug is absorbed mainly in colon. Thus, the RS-BET allow for oral delivery of small molecule, peptide, protein and microbiota as well. We focus on RS-BET encapsulated microbiota for adjuvant cancer therapy application.
Basically, the building block of RS-BET is resistant starch which was extracted from green banana. Resistant starch is composed of two type of polysaccharides: amylose and amylopectin (as indicated below).
