Dissolving Microneedles
Microneedles are an innovative drug delivery method offering a painless, minimally invasive alternative to conventional injection. These tiny needles penetrate the skin’s surface to deliver drugs or vaccines directly into the dermis, without the discomfort of a hypodermic needle.
Dissolving microneedles are made from biodegradable materials that dissolve after use, releasing the drug and leaving no sharps waste. They reduce infection risk, allow precise dose control, and improve patient compliance — making them suitable for applications ranging from cosmetic use to vaccine administration.
WCC's Multi-layer Microneedle Structure
WCC’s microneedles use a multi-layer structure, patented in multiple jurisdictions, with active ingredients incorporated at the needle tip. The layered design allows the release profile to be controlled, and the drug payload adjusted per patch.
Needles measure between 300 μm and 1,000 μm — long enough to cross the stratum corneum, short enough to avoid the pain receptors in the tissue below. Needle geometry, height, patch shape and array configuration can all be tuned to requirement.
WCC's Dissolving Microneedles Key Advantages & Mechanism
Among the various producers of dissolving microneedles, WCC Biomedical stands out with its highly specialized and advanced technology. What makes WCC Biomedical’s dissolving microneedles unique is their globally patented multi-layer structure, which is designed to enhance the precision and efficiency of drug and vaccine delivery.
The key innovation lies in the multi-layered design of the microneedles. Unlike conventional dissolving microneedles, WCC Biomedical’s microneedles incorporate the active pharmaceutical ingredients (APIs), such as drugs or vaccines, directly into the tip of the microneedles. This strategic placement ensures that the therapeutic agents are delivered accurately to skin, minimizing wastage and enhancing bioavailability. By concentrating the active ingredients in the tip, WCC Biomedical ensures highly targeted and controlled release upon administration. This technology is ideal for delivering sensitive biologics like vaccines, as well as small molecule drugs, ensuring that the correct dose is released exactly where it is most effective.
