What are Redbud Posts?
Redbud Posts are high aspect ratio, flexible, microposts that move in response to magnetic fields. They move in a wide variety of patterns, depending on the specific time-varying magnetic field to which they are exposed.
Originally developed as biomimetic cilia, these microposts have fascinating material properties. Their physical characteristics (diameter, length, and density) can be precisely controlled. So too can their chemical, elastic, and magnetic properties. The result is a rich design space that enables a wide range of practical applications. (Redbud Labs has exclusive right to practice a variety of patented inventions based on this technology.)
For example, Redbud Posts can pump and mix fluids at the microscale. This insight is at the heart of MXR, the first microfluidic mixing module designed specifically for diagnostic devices. Redbud Posts have been used as a micro-elastometer, enabling next generation blood coagulation assays in a solid-state design. At Redbud Labs, we continue to explore novel applications of micropost technology, with several innovative products under development.
A variety of additional factors make Redbud Posts perfect for next-generation life science applications:
- They are formed out of cost effective and biocompatible materials and manufactured using highly scalable soft-lithography methods.
- They can be combined with a wide range of optical analytic modalities.
- The surface chemistry can be tuned
- Reagents can be lyophilized onto the posts.
- The motion generates low shear, minimizing damage to delicate samples
- The magnetic actuation method is isothermal and Redbud Posts operate over a wide temperature range.
