Talk: Transformative Medicine via Smart SANDs, QBET, and EXODUS

Abstract

In this talk, I will present smart SANDs (Speedy Analytical Nano-optofluidic Diagnostic system) to predict and stop the spread of infectious diseases. Smart SANDs refer to advanced molecular diagnostic systems consisting of three primary components: (1) a self-contained on-chip sample preparation and liquid biopsy process, (2) an ultrafast plasmonic amplification method for DNA, RNA and protein biomarkers, and (3) a smartphone optical system interface. Furthermore, nanoplasmonic optical antennas permit QBET (Quantum Biological Electron Transfer) imaging to detect ET dynamics in mitochondrial cytochrome c in living cells. The non-invasive real-time QBET spectroscopic imaging of ET in live cells can open a new era in life sciences since it captures spatiotemporal ET dynamics in live cells. Nanoplasmonic optical antennas can also capture the secret communication codes of the bacterial extracellular vesicles (EVs) to better understand the mechanisms of bacterial communication, pathogenesis, and drug resistance.

I will also discuss how human EVs have emerged as a new paradigm in diagnostics and therapeutics, and the recent progress of EV-based applications of EXODUS (EXOsome Detection via the Ultrafast-purification System). Since the EXODUS by harmonic resonator generates high speed, purity, and yield via automated label-free purification of exosomes from various biofluids, it produces the most sensitive detection of liquid biopsy (from blood, tears, urine, or saliva). For example, the significantly improved purification of exosomes from cancer patients' urine samples enables us to obtain efficient multiomics and compare enriched pathways of kidney and bladder cancer. We also developed iTEARS (integrated Tear Exosome Analysis via Rapid-isolation System) to identify proteins and miRNAs biomarkers and see the world of diseases in a drop of tears. EXODUS-based iTEARS can provide a solution to identify numerous other diseases, including infectious diseases, neurodegenerative diseases, and cancers.

For personalized precision medicine, I will present the development of brain organoid MAP (Microphysiological Analysis Platforms) with brainwave sensors and therapeutic modulations of mitochondrial electron transport chains. Human-induced pluripotent stem cells-based brain organoid MAP provides an ideal model to address fundamental questions of neuropathogenesis and find solutions for neurodegenerations. In addition, patient-derived brain organoids can recapitulate patient responses and help personalized medicine. Smart SANDs, QBET, EXODUS, and brain organoid MAPs will impact quantitative life sciences and transformative medicine via the convergence of biology, chemistry, physics, and engineering.

Biography
