Negative refractive index materials (NRIMs)
Sponsor: AFOSR

This project focuses on the development of metamaterials that exhibit negative refractive index (NRI) at visible/infrared wavelength ranges via the rigid rod-flexible coil block copolymer-directed nanoparticles  (NPs) assembly.  The unit cell size of metamaterials, defined by the molecular structure of block copolymer and

Highly Sensitive, Selective, Self-Signal Amplifying Molecular DNA Sensors
Sponsor: National Science Foundation

Low cost, reliable detection of bio-threat agents remains a significant challenge especially given the diversity of the potential agents which can be used for this purpose. The most reliable way of identifying the identity of any virus or microbe is through its genetic code. The

Flexible Photovoltaic Cells Based on Conjugated Polymers and Nanomaterials

The current study is involved in the fabrication of self-organized composites of block copolymers and nano-semiconductors to build hetero-junction solar cells.  The block copolymers are comprised of poly(alkyl thiophene) blocks with low polydispersity and high regioregularity as energy harvesting materials as well as hole-transporting

Reversible Fluorescence Enhancement in Oxadiazole-Containing Conjugated Polymers

We have recently observed a unique phenomenon in a conjugated copolymer containing the well-documented Oxadiazole moiety. After irradiation with UV light the polymer exhibits an increase in its photo-luminescence intensity. This is exactly the opposite of normal behavior for fluorescent conjugated polymers and is considered

Dynamic Sequential Layer-by-Layer Deposition
Sponsor: Rackham, OVPR

Layer-by-Layer (LbL) multilayer film deposition method is one of the techniques widely used for the fabrication of functional materials due to its simplicity. In spite of its versatility, the LbL process is quite slow. The needs to build multilayer films fast have given birth to

Microfabrication of Super Adherent Synthetic Surface Mimicking Gecko Toes
Sponsor: NSF

The objective of the research is developing artificial surface nanostructures to mimic gecko skins. Geckos have an amazing ability to climb up and down vertical dry walls effortlessly. Recent investigations showed that the secret is due to the uniquely structured ¡°Seta¡± hairs on gecko¡¯s palms.
