Ester Segal, Professor

Research Interests:

Porous silicon, hybrid nanomaterials, optical biosensors, drug delivery.

Short Synopsis:

The research of my group lies at the broad interface between nanomaterials science and biotechnology. My research includes the basic study of structure-property relationships of nanomaterials and application of this knowledge in development of functional materials systems. We are interested in nanostructured materials (such as porous Si and inorganic nanowires) and their interface with soft matter e.g. hydrogels, biomolecules, and living cells. Understanding these interfaces allows us to rationally design biosensors for detection of biological and chemical toxins, new drug delivery platforms, and functional responsive materials.
