Coated Microneedle Development Services

Protheragen-ING specializes in the development and manufacturing of coated microneedle technology to provide innovative solutions for drug delivery systems. By coating the surface of microneedles with different drugs or carriers, we are able to further enhance their drug delivery capabilities and biocompatibility, providing patients with more convenient and effective treatments. Whether you need to customize an existing coating method or develop a new coating, our team of skilled professionals is ready to assist you.

The Concept of Coated Microneedless

Coated microneedles are an emerging multifunctional delivery system that can be used to deliver a wide range of materials, including small molecules, proteins, DNA, viruses, and even particles.

Coated microneedles contain sharp, solid microneedle structures coated with a solid membrane containing an active compound and a water-soluble inactive excipient. When a drug-coated microneedle is inserted into the skin, the coating encounters interstitial fluid present in the tissue, contact with which helps to dissolve the water-soluble excipients in the coating, which in turn triggers the separation of the coating from the microneedle surface. Coated microneedles can be used to deliver their coating payload not only to the skin but also to other tissues.

Our Coating Approach

In our coated microneedle development services, we utilize advanced coating technology to ensure that the drug is uniformly distributed on the microneedle surface and provides optimal drug release properties. Our team of experts will develop the optimal coating solution according to the client's requirements and drug properties to ensure the stability and activity of the drug during delivery.
