Latest Patents

Polak's latest patents include groundbreaking advancements in targeted drug delivery and nanocomposite fabrication. One of her notable inventions is the development of synthetically functionalized living cells for targeted drug delivery. This technology allows for the attachment of uniform, functional polymer patches to a fraction of the surface area of living individual cells. These surface-modified cells can effectively cross the blood-brain barrier while remaining viable after the attachment of the functional patch. The functional payloads carried by the patch can include various drugs, and the patch can consist of one or more polyelectrolyte multilayers (PEMs).

Another significant patent involves a spray-coating method with particle alignment control. This simple spray coating process can create epoxy/HNT nanocomposites with vertically aligned nanotubes. By controlling the level of nanotube dispersion during processing and the final orientation of the nanotubes, important mechanical properties such as modulus and hardness values can be optimized and enhanced. This innovative processing scheme allows for the fabrication of HNT nanocomposites with a high level of control over nanotube alignment and the resulting mechanical properties.
