4. U-Strip from Transdermal Specialties

Pennsylvania's Transdermal Specialties has high hopes for its innovative insulin system using its U-Strip platform. The tech is an external patch that uses alternating ultrasonic waves to expand pores, allowing for large-molecule drugs to get through the skin and into the bloodstream non-invasively. Transdermal Specialties unveiled an insulin-delivery application for the platform this month at the American Diabetes Association's convention and is in the midst of clinical trials with hundreds of Type 1 and 2 diabetics. The system is designed to be compatible with smartphone-based glucose monitors, and Transdermal Specialties is planning to get it approved and on the market by 2014.
