Three major microneedle classes and six technology variants
Microneedles are typically several hundred micrometers long. They pass through the stratum corneum to form micron-scale pathways without reaching the deeper nerve-rich tissue, enabling localized or systemic delivery with improved usability.
A drug coating is applied to a water-insoluble microneedle surface and released rapidly after insertion, supporting low-dose and precision delivery.
Water-soluble pharmaceutical polymers carry active ingredients within the needle matrix or tip; the structures dissolve after insertion and release the payload.
Water-insoluble structures swell after insertion to form hydrogel pathways through which larger payloads can diffuse; the array is removed intact after use.
The platform covers microneedle structure design, formulation and process development, analytical evaluation and translational research for peptides, proteins, vaccines, natural products and small molecules.
