Title: Innovations of John H Holtz

Introduction

John H Holtz is a notable inventor based in Pittsburgh, PA (US). He has made significant contributions to the field of sensor technology, holding a total of three patents. His work primarily focuses on the development of novel sensor devices that utilize polymerized crystalline colloidal arrays.

Latest Patents

Holtz's latest patents include innovative sensor devices composed of a crystalline colloidal array (CCA) polymerized in a hydrogel. These hydrogels are designed to shrink and swell in response to specific stimuli. As the hydrogels undergo these changes, the lattice structure of the embedded CCA alters, resulting in a change in the wavelength of light diffracted by the CCA. By monitoring this change in diffracted wavelength, the concentration of a stimulus can be accurately determined. The gels can be modified to sense various stimuli, making these sensor devices highly specific to react with only one species or family of species. The applications of these sensors span across environmental and chemical systems, chemomechanical systems, sensor devices, and medical diagnostic tools. Holtz has also disclosed various methods for making and using these devices.
