Microneedles Are Being Developed For a Variety of Applications [1-4]:
Optimize your required microneedle properties with VivoSight imaging and measurement tools.
Translational research leading to practical applications [1 – 4]:
“VivoSight OCT is essential for our microneedle research and for the development of related devices and applications. The ability to visualize polymeric microneedles in-vivo allows for measurement of the exact depth of penetration. Moreover, OCT allows us to monitor swelling and dissolution kinetics of biodegradable needles. It is an indispensable tool to advance and optimize Microneedle Array Patch (MAP) research and product development”.
