Singamaneni’s research interests include Plasmonic engineering in nanomedicine (in vitro biosensing for point-of-care diagnostics, molecular bioimaging, nanotherapeutics), photovoltaics (plasmonically enhahced photovoltaic devices), surface enhanced Raman scattering (SERS) based chemical sensors with particular emphasis on the design and fabrication of unconventional and highly efficient SERS substrates, hierarchical organic/inorganic nanohybrids as multifunctional materials, bioinspired structural and functional materials, polymer surfaces and interfaces, responsive and adaptive materials and scanning probe microscopy and surface force spectroscopy of soft and biological materials.
Engineers have created a bacteria-filtering membrane using graphene oxide and bacterial nanocellulose. It’s highly efficient, long-lasting and environmentally friendly — and could provide clean water for those in need.
The associate professor in the School of Engineering & Applied Science works to create powerful sensors that can detect chemicals, biomarkers that could speed health-care diagnostics and new materials to clean dirty water.
Researchers at Washington University in St. Louis, led by Srikanth Singamaneni, PhD, associate professor of materials science in the School of Engineering & Applied Science, are using color-shifting nanoparticles of gold, combined with specifically engineered artificial antibodies, to detect biochemical signs of kidney damage.
