Abstract:
|
Technical textiles for medical applications are a
research expanding field. One of the added values of these
materials can be suitable to contain and release active ingredients
in a controlled manner. A possible alternative to obtain fabrics
with controlled drug release properties could lie in the
modification of fiber-active principle bonds, so that you get a
proper release for each particular application. R & D currently
developing drug delivery systems aims to achieve a controlled
release of an active principle during a predetermined time. This
is done in order to avoid the administration of several doses of
drugs or cosmetic products and thus make the patient follow the
therapy more easily.
The influence of surface modification of fibers by low
temperature plasma has been studied regarding the modification
of the physical, chemical and topographical properties of the
textile fibers. First studies evaluated the incorporation and
release of anti-inflammatory and cosmetic drugs from different
textile materials to evaluate the modulation of the drug release as
the result of the surface modifications achieved by plasma
treatment. The use of plasma technology to modulate the release
of drugs is an original and innovative contribution. By altering
the chemical bonds on the surface of textile fibers with plasma,
the drug release kinetic profiles may be modified. |
