Encapsulation of Fluorescent Nanodiamonds into Poly-dopamine (PDA) Shell and Further Covalent Functionalization of the PDA Shell for Diagnostic Imaging Applications

This technology includes a new class of nanoparticles in the carbon family, fluorescent nanodiamonds (FNDs), exhibiting superb physical and chemical properties for diagnostic imaging applications. We have developed a simple, fast, and robust method to encapsulate FNDs in polydopamine that can be further functionalized. By integrating anatomical and...

Background-free Imaging by Selective Modulation of Nanodiamond Fluorescence Using a Magnetic Field

This technology includes the use of nanodiamonds to achieve background-free imaging. We present several techniques to reduce or eliminate background florescence by exploiting properties of the fluorescent nanodiamonds. In particular, magnetic field modulation of the fluorescence intensity offers a simple, robust, and easily adaptable method to obtain...

Highly Sensitive Tethered-Bead Immune Sandwich Assay

This technology is a highly sensitive tethered-bead immune sandwich assay. Analyte molecules are captured between two antibodies, a capture antibody and a detection antibody. The capture antibody on a micron-size bead binds analyte from a sample fluid. The bead-captured analyte is then exposed to a “detection” antibody that binds to the bead-captured...

Fluorescent Nanodiamonds as Fiducial Markers for Microscopy

The invention relates to fluorescent nanodiamonds (FNDs) and their uses as fiducial markers for microscopy. FNDs are bright fluorescent probes that do not blink or bleach and have broad fluorescence excitation and emission peaks. The fluorescence intensity can be readily controlled by the size of the FND, the number of fluorescent centers produced...
