Title: Innovations of Timothy J Johnson

Introduction

Timothy J Johnson is an accomplished inventor based in Charlestown, MA (US). He holds a total of 4 patents that showcase his contributions to the field of microfluidics. His work focuses on developing innovative devices and methods that enhance the efficiency of fluid manipulation.

Latest Patents

One of his latest patents is a microfluidic flow manipulation device. This apparatus and method facilitate the mixing of two microfluidic channels, where several wells are oriented diagonally across the width of a mixing channel. The device effectively mixes confluent streams using electrokinetic flow, and to a lesser extent, pressure-driven flow. It can also adapt to split confluent streams into two or more streams with varying concentrations of reactants. Additionally, the surfaces of the wells can be specially coated to improve mixing efficiency by leveraging differing electroosmotic mobility. Another significant patent involves surface charge modification within preformed polymer microchannels. This method allows for the modification of channels made from various substrate materials, including PMMA. It can modulate electroosmotic flow and immobilize chemical compounds or biological species at modified surfaces, thus enhancing the functionality of microfluidic systems.
