Drug-releasing textiles functionality

A variety of test methods are used to characterise drug-releasing textiles however, the main characteristics that are commonly determined are mechanical properties, morphology, degradation, chemical functionality, and of course drug-loading capacity and release kinetics. 

Previous papers have investigated the suitable use of xylan in papermaking [10] and textile printing [21]. In the drug delivery field, xylan extracted from birch wood has been used for the production of nanoparticles after structural modification by the addition of different ester moieties, namely those with furoate and pyroglutamate functions [21]. On the other hand, the esterification of xylan from beech wood via the activation of the carboxylic acid with iV,iV -carbonyldiimidazole has been carried out in order to produce prodrugs for ibuprofen release [10, 21, 22, 37]. 

Capsulation of substances in polyelectrolyte microcapsules is a perspective task to make storage and controlled transport systems to be used in chemical technology for substances transport to the reaction zone to create active corrosion prevention coatings, to produce microreactors. These systems can be applied in perfumery or in textile industry to create "smart clothers", in medicine to transport toxic drugs,in tissue and organ engineering. As a result, implementation of remote control over capsule shells permeability to release their contents controllably becomes an actual task that requires shells functionalization.
