Latest Patents

One of Dubowski's latest patents is a photo-electrochemical biosensor that utilizes a semiconductor heterostructure located in an etching solution. This biosensor features an outer layer that is functionalized to adhere to charged molecules of interest. When a test solution is introduced, the functionalization immobilizes a quantity of the molecule corresponding to its concentration. The heterostructure undergoes photocorrosion when illuminated by a laser, and the rate of this photocorrosion is monitored to determine the concentration of the molecule in the test solution. The use of photoluminescent materials in the heterostructure enhances the monitoring process, as the emitted photoluminescence changes with the advancement of photocorrosion.

Another notable patent involves a multilayer microstructure and a laser-based method for precision patterning. This method addresses the challenge of damaging organic or polymeric materials during laser patterning of conductive metal electrodes. By applying a thin anti-reflective coating on top of the metal electrode, Dubowski's method allows for the use of a lower fluence laser, achieving higher patterning resolution without significant ablation of the underlying materials. This innovation is crucial for producing higher quality integrated circuits.
