Latest Patents

Chad E Reese holds a patent for "Polymerized crystalline colloidal array chemical sensing materials for use in high ionic strength solutions." This novel method utilizes polymerized crystalline colloidal array (PCCA) chemical sensing materials to detect specific chemical species in high ionic strength solutions, such as bodily fluids. The PCCA sensors consist of a mesoscopically periodic array of colloidal particles polymerized into a hydrogel. The periodic spacing of these particles allows them to diffract light in the visible spectral region. The PCCA materials also incorporate molecular recognition components that bind to the chemical species being detected. The binding results in a Donnan potential that swells the hydrogel, causing a red shift in the diffracted light that is proportional to the concentration of the chemical species. The method involves incubating the PCCA sensor in the sample solution and then exposing it to a low ionic strength solution to measure the transient diffraction shift response.
