  • Publication number: 20230341407
    Abstract: Methods and systems for characterizing extracellular vesicular biomarkers using a biochip with gold nanoparticles. The biochip includes a glass surface, a gold film layer on the glass surface, a plurality of gold nanoparticles coupled to the gold film layer, and a plurality of biotinylated antibodies coupled to the gold nanoparticles. In some implementations, the gold film layer of the biochip is coated with polyethylene glycol (PEG). The biotinylated antibodies are selected to capture specific types of extracellular vesicles. PD-L1/PD-1 proteins and RNAs in extracellular vesicles were characterized for cancer immunotherapy.

  • Publication number: 20220026419
    Abstract: The present invention disclosed a method of fabricating an antibody immunolipoplex nanoparticle (Ab-ILN) biochip and antibody tethered lipoplex nanoparticle (Ab-TLN) biochip. The aforementioned antibody-based lipoplex nanoparticle biochip or the related array contains molecular probes and is applied for detecting the presence of a disease or condition in a subject obtaining a body fluid sample by capturing and identifying both membrane protein and intra-vesicular DNA/RNA/proteins of extracellular vesicles (EVs).

  • Publication number: 20210332423
    Abstract: The present invention discloses a method of detecting the presence of mutated genes, mRNAs or microRNAs in a subject. The method comprises the following steps: (1) Provide a body fluid sample containing cells, circulating tumor cells (CTCs), and/or extracellular vesicles (EVs); and use an analyzer having overhang molecular beacons to measure fluorescence signals generated by interactions between the body fluid sample and the overhang molecular beacons, so as to detect the presence of the mutated genes, mRNAs or microRNA. Furthermore, a biochip comprising a gold coating substrate and tethered lipoplex nanoparticles encapsulating the overhang molecular beacons is also provided in the invention.
