TECHNOLOGY OVERVIEW

Dissolvable microneedle is a micro-dimensioned innovative platform to enhance transdermal drug delivery of compounds in a painless manner. Generally, microneedle arrays, ranging from 100 to 1000 μm in height, are manufactured over patches. This platform was initially developed to overcome the skin barrier’s permeation limitation by physically creating micro dimensioned pores and delivering the encapsulated compounds into the body. Depending on the properties of encapsulated compounds and their target site, dissolving microneedles can be fabricated in various heights and geometries. So far, a wide range of micro- and macro-biomolecules, vaccines, peptides, nano-particles, drugs, and cosmetics were successfully encapsulated within microneedles. However, the commercialization of microneedles is still limited due to their low encapsulation capacity and delivery accuracy. The technology owners have designed and developed various innovative mass-production techniques to manufacture high-capacity dissolving microneedles capable of encapsulating a larger volume of encapsulated compounds compared with conventional microneedles. Through these technologies, the delivery effectiveness of encapsulated cosmetics and drugs can be immensely improved. In addition, these technologies can be utilized as universal platforms for encapsulation of various micro- and macro-biomolecules. The technology owners would be interested in establishing academic and business cooperation with universities, R&D centers, biopharmaceutical enterprises, and cosmetic companies to apply the developed technologies in various fields.

TECHNOLOGY FEATURES & SPECIFICATIONS

The proposed technology has the following features: High-capacity geometry: improves the delivery effectiveness of compounds Flexible geometry: with the proposed technology, microneedles can be designed and adjusted based on the target compound and application sites Precise delivery accuracy: overcomes the skin barrier’s permeation limitations Universal platform: capable of encapsulating a wide range of compounds Innovative technology: dissolving microneedles are an innovative technology that can be used as a marketing strategy to differentiate a manufacturer’s product from others.

POTENTIAL APPLICATIONS

The offered microneedle fabrication technologies are applicable in both pharmaceutical and cosmeceutical enterprises, as they can encapsulate their compounds within microneedles and create new markets for their products. In addition, dissolving microneedles can be utilized as a potential replacement for hypodermic injections to reduce pain and patient inconveniences. There are a wide range of ongoing researches optimizing encapsulation of vaccines, peptides, anti-obesity drugs, and anti-diabetes compounds within microneedles to replace hypodermic injections. Interested enterprises can cooperate with the technology owners to perform the feasibility tests and the related experiments as well.
