  • Publication number: 20200116729
    Abstract: The present disclosure relates to a novel method for lateral flow immunoassay (LFIA) by utilizing plasmonic enhancement strategy. More specifically, the present disclosure provides a plasmonic enhanced lateral flow sensor (pLFS) concept by introducing a liposome-based amplification of the colorimetric signals on the lateral flow platform for ultrasensitive detection of pathogens.

  • Patent number: 9968692
    Abstract: The present invention provides a nanobubble comprising a continuous outer shell, the outer shell comprising a cross-linked polymeric material, an inner wall of the continuous outer shell and a hollow core within the continuous outer shell. The nanobubble may be less than 250 nm in diameter. In a further aspect of the invention, the cross-linked polymeric material is a cellulose-based material.

  • Publication number: 20120164717
    Abstract: An apparatus and method of characterizing cells having surface markers includes the use of functionalized probes, the probes having absorption spectra characteristic of a probe geometry. The probes are functionalized with biomolecules (biomarkers) capable of binding to the surface markers, and cells having a particular combination of probes having specific bound biomarkers are measured using a spectrum analyzer. A plurality of surface markers may be simultaneously measured using the spectral properties of the probes to differentiate the cells. The relative abundance of a plurality of surface markers may be determined simultaneously. Functionalized probes with several different aspect ratios were used in an experiment to demonstrate the use of functionalized probes for characterizing cancer cells. The functionalized gold nanorod probes when attached to magnetic particles may be used as a dual contrast agent for magnetic resonance imaging (MRI) and optical imaging and as a targeted drug delivery system.
