Title: Innovations of Ho Cheung Shum
Introduction
Ho Cheung Shum is a prominent inventor based in Hong Kong, CN. He has made significant contributions to the field of microfluidics, holding a total of 10 patents. His work focuses on developing innovative systems that enhance the efficiency and accuracy of droplet manipulation and encapsulation.
Latest Patents
One of his latest patents is the "Automatic microfluidic system for continuous and quantitative collection of droplets." This automatic system integrates a three-branch sorter with independently-controlled valves and corresponding collection platforms. The system effectively sorts subgroups of droplets into three channels, which are then pumped into PCR tubes. Experimentally, it has demonstrated the ability to accurately collect droplets across a large working range, accommodating both pure positive samples and mixed samples with negative ones. This technology lays the groundwork for advancements in digital droplet microfluidics.
Another notable patent is for "Core-shell capsules for encapsulation of particles, colloids, and cells." This patent describes methods for preparing micro- and nanocapsules from all-aqueous emulsions. The process involves mixing a first electrically charged phase with a second phase containing a second solute, which are incompatible with each other. The electrostatic forces between the two solutions lead to the formation of droplets, which are then solidified to create the capsules.
