Application

NanoFabTx Polymers for Microneedles are carefully selected polymers that can be used to formulate microneedle patches. Microneedles are tiny projections of needles approximately 400-800um in length arranged in a small 1cm x 1cm patch. Microneedles are composed of blends of synthetic or natural polymers at suitable concentrations. Sodium hyaluronic acid (HA) is the derivate of a natural polymer and is a natural polysaccharide. It is a water-soluble polymer and is available in different molecular weights. The formation of the microneedles depends on the molecular weight and concentration of HA.


The NanoFabTx Polymers for Microneedles can be used with the microneedle templates to formulate microneedle that can be used for several applications, such as delivering various therapeutic molecules and vaccine antigens via the skin. The selected polymer will enable users to:

1)save time in selecting the polymer and provide a starting point to formulate microneedles by avoiding lengthy trial-and-error optimization.

2)formulate microneedles for various drug delivery applications.

Effective vaccines delivered via painless methods would revolutionize the way people approach vaccinations. This study focused on the development of fast-dissolving microneedles (MNs) to deliver antigen-loaded sustained release polymeric nanoparticles (NPs), achieving a dual-delivery platform for vaccination through the skin.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
