Abstract: Protein drugs, for e.g. hormonal drugs cannot be
delivered orally to a patient as they get digested in
the gastro-intestinal (GI) tract. Thus, it is
imperative that these kinds of drugs are delivered
transdermally through the skin. To provide for a
real-time feedback as well as to test independently
for various substances inside the blood, we also
need a blood sampling system. Further,
microneedles made of silicon or metal have the risk
of breaking inside the skin thereby leading to
complications. Thus, here we present very tall
(around 1600 microns) SU-8 polymer-based hollow
microneedles fabricated by a simple, low-cost and
repeatable process, which are a very good
candidate for transdermal drug delivery as well as
blood extraction.
