Physicist Receives $1.17 Million NIH Grant to Create ‘Nanobiosensors’
Liviu Movileanu, associate professor of physics in the College of Arts and Sciences, has received a $1.17 million grant award from the National Institute of General Medical Sciences, which is part of the National Institutes of Health (NIH). Movileanu will use the award, which is also funded by the National Nanotechnology Initiative, to support his work with “Engineered Nanopores for Single-Molecule Stochastic Sensing.”
Movileanu and his team will design and develop nanobiosensors, which are nanomaterials used for the detection, characterization and analysis of protein interactions. Their research will presumably lead to accelerated discoveries in fundamental and clinical molecular biomedical diagnostics, which, in turn, could improve the prognosis and detection of cancers. It may also pave the way for more accurate profiling of protein biomarkers, which are useful for the early detection of disease.
“I am grateful for the NIH, without whose support I could not engage in such cutting-edge biophysical research,” says Movileanu, who joined Syracuse’s faculty more than 10 years ago. “By creating a new generation of research tools in nanomedicine, we aim to help doctors detect cancers and other diseases more quickly and accurately, as well as less expensively. This is going to happen through the detection of tiny amounts of specific proteins that are in greater concentrations under pathogenic contexts than otherwise in normal cells.”
Central to Movileanu’s work are enhanced nanopore technologies, which help him examine complex biochemical events in a quantitative manner. He says the needs for such technologies are “pressing,” if not “urgent.”
“What we do is aimed at expanding nanopore technology to that of real-time protein detection and analysis,” Movileanu explains. “It represents a critical step towards the creation of high-throughput screening devices for targeted protein sampling. This means that the same device will contain specific engineered nanopore elements for the detection of hundreds of distinct protein biomarkers, which is really a practical problem that needs to be addressed. In an ideal world, you can say that a quick blood test will provide a complete knowledge about a certain patient.”
“The Department of Physics is proud of Liviu’s continuing success and of this recognition for his research program,” says A. Alan Middleton, professor and chair of the Department of Physics. “His efforts show how fundamental research can lead to surprising new applications. The development of new nanopore devices, the result of exploratory science and innovation, is expected to directly improve medical research and diagnosis.”
