Latest Patents

One of her latest patents is titled "Detection and identification of biological agents using Bragg filters." This innovative method involves sensing environmental agents by obtaining a sample and transferring it into a working fluid for analysis. The mixture is then filtered through a porous polymer Bragg grating, allowing for the identification of hazardous agents based on differences in refractive indices. Additionally, the sensor functions as a chemical filter, trapping specific target agents through a highly specific reaction with a conjugate molecule. The system is designed to be 'always on' by recirculating the working fluid.

Another significant patent is "Tailoring material composition for optimization of application-specific switchable holograms." This process optimizes the performance parameters of holograms by reducing scattering effects in polymer-dispersed liquid crystal optical elements. The method involves adding an interfacial tension agent to the liquid crystal material, which helps reduce the size of liquid crystal droplets during polymerization, enhancing the overall performance of the optical element.
