Engineered Core-Shell Cu particles demonstrate strong potential for plant disease control

Young M., Ozcan A., Myers M.E., Graham J.H., Santra S., University of Central Florida, US

Copper (Cu) bactericides/fungicides are used extensively for crop protection in agriculture. There is an increasing concern for Cu accumulation in fertile soil and potential for Cu leaching into the surrounding ecosystem. Moreover, development of Cu [...]

Fluorescent quantum dot as model imaging probe for studying plant uptake, systemic mobility, localization in plant tissue and potential fate of ultra-small nanoparticles

Das S., Tharkur J., Tetard L., Gesquiere A., Santra S., University of Central Florida, US

Semiconductor fluorescent quantum dots (Qdots) are popularly used as bioimaging taggants in live cell imaging and spectroscopy. In recent years, Qdots taggants are emerging in agricultural applications. Studies are primarily focused on nanotoxicity of ultra-small [...]

From Rational Design to Probe Optimization: the Role of Nanoparticle Valency in Single Cancer Cell Detection in Blood via Magnetic Relaxation

Kaittanis C., Santra S., Perez J.M., University of Central Florida, US

The conjugation of targeting ligands to iron oxide nanoparticles has achieved the development of specific assays for the detection of biomedical targets through magnetic relaxation. However, limited studies investigated how the nanoparticle valency modulates the [...]

Identification of Molecular-Mimicry-Based Ligands for Cholera Diagnostics using Magnetic Relaxation

Santiesteban O.J., Kaittanis C., Banerjee T., Santra S., Teter K., Perez J.M., University of Central Florida, US

Magnetic nanosensors (MRnS) offer multiple benefits that can be used to design sensitive and robust diagnostic tools. High sensitivity, stability, and ease of surface modification make this approach a strong contender against the more commonly [...]

Intrinsic oxidase activity of cerium oxide nanoparticles facilitate the detection of cancer biomarkers and cancer cells

Perez J.M., Asati A., Santra S., Kaittanis C., Nath S., University of Central Florida, US

Nanomaterials exhibit unique size-dependent physical properties. Thus, identifying novel properties of these materials at the nanoscale, and their applications in energy, catalysis and medicine, among others, is an area of current and intense research. Cerium [...]

Quantum Dots for Multimodal Bioimaging and Sensing Applications

Santra S., Yang H., Sabui S.K., Sharma P., Holloway P.H., Walter G.A., Moudgil B.M., Scott E., University of Central Florida, US

Fluorescent quantum dots (Qdots) have demonstrated their potential in diagnostic bioimaging applications in vitro. For in vivo bioimaging applications, however, the embodiment of additional properties such as paramagnetism onto the same fluorescent probes is highly [...]
