MICRONEEDLE PATCH: BACKGROUND
Creation of the Microneedle Patch
The microneedle patch is composed of several needles attached to a flat patch. Small caches in the patch hold treatments that are expelled out through the needles. After use, the patch can be disposed of in normal waste containers. Nanoparticles are primarily stored in the cache deposits, becoming efficient drug carriers for the molecules that will enter the body.
The needles of the patch are also composed of water soluble polymers that dissolve into the skin's dermal layers. This specific region of treatment allows for the needles to directly target the Lagerhan cells to directly vaccinate the immune system without directly entering the bloodstream, requiring lower dosages than the standard needle injections.
WHEN AND WHERE?
The microneedle patch is now been used for several purposes, but the innovation's initial purpose was to deliver medication through the patch. Seeing a need for a cost-effective and painless method of drug delivery, researchers at Drug Delivery Systems Inc. sought to develop the patch for communities that lack the infrastructure and resources to have standard needle injections.
The patch faces challenges of distribution. Specifically, while cutting on transportation costs, microneedle patches are more expensive than standard needles to manufacture, and therefore, researchers face challenges in developing a microneedle patch that is both inexpensive to produce and effective for the public.
The patch has made significant improvements pushing it toward clinical stages of testing. From innovators developing small pores to maximize treatment delivery, or clinical research initiatives where researchers first vaccinate Papua New Guineans, the microneedle patch is constantly changed and improved to make the patch more easy to transport and quicker to deliver drugs.
The patch was first developed in the United States in the '90s, but since then, the microneedle patch has continuously changed and developed across the globe.*
In Australia, the United Kingdom, and the United States of America, the patch has been developed as a vaccination and treatment tool. **
In Papua New Guinea, the patch has been tested to help vaccinate communities cost effectively. In South Korea, the patch has been developed primarily to serve as a cosmetic treatment.***
The patch has proven much of its abilities and potential in many clinical studies. In the future, the patch's abilities will be first applied to creating vaccines for HPV and polio and released for public use. In doing so, this cheap, durable, and easy application drug delivery technique could vaccinate the globe leading toward the irradiation of more diseases
