Microneedle Patches Coating Process
Microneedle patches, also known as microarray patches, are micron-level medical devices that play an important role in the medical field. They are mainly used for the injection of vaccines, drugs, and other therapeutic agents. The initial application of microneedles was focused on transdermal drug delivery. With the continuous development of technology, its application range has expanded to drug delivery in the eye, vagina, nail, heart, blood vessels, gastrointestinal tract, and cochlea.
The construction of microneedles requires the use of a variety of methods, among which photolithography and micromolding are more common. The principle of these methods is to etch microstructures into resin or silicon materials and then cast microneedles.
Coated microneedles are made by coating a drug solution on a solid microneedle. The thickness of the drug layer can be flexibly adjusted according to the required drug dose. Compared with other routes of administration, coated microneedles have a significant advantage, that is, less drug is required. This is because the drug layer can dissolve quickly and directly penetrate the skin into the systemic circulatory system.
In the drug coating process, ultrasonic spray technology is of great application value. It can precisely deposit drug delivery systems or gene therapy coatings onto microneedle patches or arrays, not only achieving repeated deposition of thin films on the needle tips, but also avoiding unnecessary material accumulation on the substrate, thereby achieving precise dose control.
