Introduction

Gerardus F Steeghs is a notable inventor based in Geldrop, Netherlands. He has made significant contributions to the field of biomedical engineering, holding 2 patents that showcase his innovative approaches to technology.

Latest Patents

One of his latest patents is a method of providing a substrate with a layer comprising a polyvinyl base hydrogel and a biochemically active material by photolithography. This method involves coating the substrate using centrifugal force with an aqueous solution of a photosensitive hydrogel forming polymer, a crosslinking agent, and a biochemically active material. The process includes drying the coating, exposing it through a photomask to ultraviolet radiation, and developing the exposed coating. This invention is characterized by the application of an aqueous solution that includes a polyazonium compound and glutaraldehyde as cross-linking agents, which results in superior binding properties for the biochemically active material.

Another significant patent is for a polarographic-amperometric three-electrode sensor, particularly designed for biomedical use. In this invention, a working electrode and a reference electrode are covered by an electrolyte layer, separated from the medium to be measured by a semipermeable membrane. The counter electrode is proposed to be an external electrode, which can be an outer metal coating surrounding the sensor chip. This innovative design allows for the creation of a micro-sensor using integrated techniques, with materials such as stainless steel or conductive plastics.
