Title: Innovations by Paul Chi Hang Li
Introduction
Paul Chi Hang Li is a notable inventor based in Coquitlam, Canada. He has made significant contributions to the field of technology with a focus on innovative testing devices and microfluidic systems. With a total of 3 patents to his name, his work exemplifies the intersection of simplicity and advanced technology.
Latest Patents
One of his latest patents is a device for test strips that allows for the visual differentiation of liquid mixture compositions. This test strip exhibits visual changes, such as color changes, when there is only a slight difference in the composition of liquids like gasoline, oil, ethanol, and water. Such subtle differences typically require sophisticated and expensive instruments to detect. The test strip consists of one or more inverse opal films deposited on a substrate, achieving differentiation in a simple, fast, and energy-free manner.
Another significant invention by Li encompasses microfluidic microarray assemblies and methods for their manufacture and use. In this invention, first and second channel plates are sealingly connected to a test chip in consecutive steps. Each plate includes microfluidic channels configured in a predetermined reagent distribution pattern. The test chip comprises multiple discrete test positions, each located at the intersection of a first and a second predetermined reagent pattern, with at least one of the patterns being non-linear. This innovative design allows for the effective distribution of reagents on the test chip.
