Functionalization of Polymethylmethacrylate (PMMA) Surface by Amination with Polyethyleneimine (PEI) for Applications in Microfluidic Immunoassays, Protein/Enzyme Biochips, and Biocatalysis
TS-037631 — Polymethylmethacrylate (PMMA) is a useful material for development of assays, biochips, and other biological materials. However, PMMA makes for a difficult substrate because of complexities with respect to adhesion. This technology presents two new methods for enhanced protein binding onto PMMA.
Polymethylmethacrylate (PMMA) is a synthetic resin in the acrylic family, often used as a substitute for glass or as a material for biomedical devices. PMMA-based biosensors have low protein binding efficiency and low sensitivity. PMMA is used in a variety of applications like immunoassays, biosen…

Multichannel Polymer Chips for Rapid Multiplex Enzyme-Linked Immunosorbent Assay
TS-014978 — A more accurate, cost efficient and faster method to one of the most widely used diagnostic tests in the world.
The conventional Enzyme-Linked Immunosorbent Assay, or ELISA, is typically carried out in a 96-well or 384-well microliter plate. The method involves a series of mixing and washing steps, which are not only tedious and laborious, but which also often result in large errors and inconsistent outcome…
