Ultrasonic Spray Coating for Microneedle Coating

Ultrasonic Spray Coating for Microneedle Coating – Cheersonic

Ultrasonic spray has emerged as a highly effective and versatile method for depositing precise drug delivery or gene therapy coatings onto microneedle patches or arrays, a breakthrough that bridges advanced drug formulation and minimally invasive administration. Unlike conventional coating techniques, which often suffer from uneven deposition or excessive material waste, ultrasonic spray leverages high-frequency ultrasonic vibrations to transform liquid formulations into fine, uniform droplets, ensuring optimal adherence and bioactivity of the therapeutic agents.

Precise dosing, a critical requirement for therapeutic applications, is reliably achieved by repeatably depositing ultra-thin films exclusively on the tips of the microneedles, while minimizing or eliminating unwanted collection on the base substrate. This targeted deposition is made possible by the unique combination of ultrasonic atomization and controlled airflow, which guide the droplet stream directly to the desired area with exceptional accuracy. The ability to maintain consistent film thickness—often measured in nanometers to micrometers—ensures that each microneedle delivers the exact therapeutic dose, reducing variability and enhancing treatment efficacy.

The gently atomized spray offers remarkable flexibility: it can be precisely targeted and controlled to deposit coatings where needed, whether with or without the use of masking tools. When masking is employed, it enables the creation of complex, patterned coatings for specialized applications, such as combining multiple drugs on a single microneedle array. Without masking, the technique remains efficient for uniform coating of standard microneedle designs. This versatility, combined with its compatibility with a wide range of therapeutic formulations—from small-molecule drugs to delicate gene vectors—makes ultrasonic spray an indispensable tool in the development of next-generation microneedle-based drug delivery systems.
