Current Research

  1. Immunoassay and bioassay
    • Developed a “lock-in” fluorescence biosensing method that can detect single biomolecules with ultrahigh sensitivity (four orders higher than ELISA), specificity, and reliability.
    • Developed ultrasensitive immunoassay and bioassay based on the “lock-in” fluorescence biosensing technique for quantitative analysis of botulinum neurotoxin (BoNT/A), westnile virus (WNV), mycobacterium tuberculosis (TB) and human α-thrombin, etc.

  2. Biomolecule nanopatterning
    • Developed a novel dynamically configurable heterogeneous biomolecular nanoarray in which the packing density, ratio and reactivity of the biomolecules on each array element can be configured quantitatively and temporally.
    • Developed a technique to pattern biomolecules carried by nanoparticles to form heterogeneous biomolecular nanoarrays, and transfer the biomolecular nanoarray to biocompatible or biodegradable polymers without losing their bioreactivity.

  3. Gene delivery
    • Developed a technique that applied patterning of drugs/genes towards controlled and localized drug/gene delivery with enhanced delivery efficiency and nanoscale accuracy for therapeutic applications and intercellular communications.
    • Demonstrated patterning of heterogeneous PEI/DNA polyplex arrays on biocompatible/biodegradable polymers to guide cell differentiation.
    • Demonstrated the ability to genetically modify mesenchymal stem cells (MSCs) seeded on the top of the PEI/DNA polyplexes arrays to form heterogeneous cell arrays.
