Acoustically Triggered Nano/Microscale Propulsion Devices

Technology Application

Applications of the invention include in vivo drug delivery, artery cleaning, biomolecular/cellular delivery, tissue sampling, crossing the blood/brain barrier, tissue penetration for triggering immune responses and/or targeted gene regulation schemes.

Detailed Technology Description

University researchers have developed new nano/microscale propulsion devices (NMSPD) that utilize ultrasound to externally trigger on-board fuel (i.e., perfluorocarbon emulsions), bound within the device interior, for ultrafast NMSPD propulsion. The invention includes methods of fabricating the NMSPD devices. The NMSPDs are biocompatible and accelerate quickly, reaching high average velocities (> 6 m/s) that are more than 100 times faster than conventional micromachines. The high thrust of the devices enables piercing, puncturing, deep penetration, deformation, and tearing apart of tissue (e.g. when fired into lamb kidney sections). Firing can also be oriented magnetically and multiple NMSPDs can be fired simultaneously. The core technology is scalable and flexible in terms of shape, design, materials used, fabrication process and external triggering source.
