She has made significant contributions to the field of biochemistry, particularly in the study of enzymes and their applications in treating diseases. With a total of 2 patents, her work has garnered attention for its potential impact on health and medicine.

Latest Patents

One of her latest patents is focused on a method of modulating radical formation by mutant CuZnSOD enzymes associated with familial amyotrophic lateral sclerosis (FALS). This patent highlights the discovery that mutant CuZnSODs A4V and G93A catalyze the generation of hydroxyl radicals from hydrogen peroxide at higher rates than the wild type. The research indicates that the copper chelator diethyldithiocarbamate (DDC) can inhibit both radical generation and SOD activity of these mutant enzymes at significantly lower concentrations than required for the wild type. In a neural cell culture model of FALS, DDC was shown to reverse the effects of four FALS-associated mutants, suggesting a potential treatment pathway for patients with mutant CuZnSOD enzymes.

Another notable patent involves a sol-gel encapsulated enzyme. This innovation describes a process where an active biological material is encapsulated in a glass using a sol-gel method. The process involves mixing a metal alkoxide with water and exposing it to ultrasonic energy, resulting in a transparent porous glass that retains a high level of activity of the encapsulated biological material.
