Congratulations to Michelle Packard and Shannon McGraw for each receiving a SMART graduate fellowship from the Department of Defense starting in fall 2008! The fellowship is for a period of 3-5 years!

Congratulations to Brian Andrew Castro and Romali Ranasinghe for each receiving second place poster award at the 2008 UURAF!

Our lab has produced 2 NSF Graduate Fellows (1 current), 2 DHS Undegraduate Scholars (1 current), and 2 SMART Fellows (current)!

Welcome to the Nano-Biosensors Lab!

Our research focus is on the development of nanostructured biosensors for homeland security and biodefense, food safety, environmental quality, and healthcare.

Research Activities

Our goal is to develop nanostructured biosensors for high-throughput detection and point-of-care diagnostics of infectious disease agents for the protection of public health, food supply chain, and economic infrastructures!

Nano-biosensors are diagnostic tools that can provide rapid results, are highly sensitive, simple to use, inexpensive, and ... can be carried around in your pocket!

We do an integrated approach to nano-biosensor development: Preparation, functionalization, synthesis, design, fabrication, and validation of biosensor devices, including the synthesis of aptamers and nanoparticles, and validating these biosensors in cultured targets and sample matrices.

* Biological and biologically-derived receptors used in our biosensors: aptamers, DNA probes, antibodies, cells, and enzymes

* Nano-transducers used in our biosensors: electrically active and magnetic nanoparticles; molecular nanowires and nanotubes

* Validation in biological matrices: food, water, serum

* Targets: Infectious disease agents

New! "Green" biogenic gold nanoparticles: 30 nm and 8 nm in diameter.

You can determine on site whether the water is safe to drink or your food is safe to eat.

You can determine if a "white powder" in your mail is harmful to you.

You can manage personal health issues in the comfort of your home. ...

The researchers in the Nano-Biosensors Lab are working hard to create diagnostic devices that may facilitate the coming of this kind of world.
