Nanomedicine via SANDs, QBET, EXODUS, and Brain Organoid MAP

【Abstract】

In this talk, I will present smart SANDs (Speedy Analytical Nano-optofluidic Diagnostic systems) 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 understand better 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 urine samples of cancer patients 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 biomarkers of proteins and miRNAs and to 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 nanomedicine, I will present the development of brain organoid MAP (Microphysiological Analysis Platforms) with quantum biosensors 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 precision nanomedicine via the convergence of biology, chemistry, physics, and engineering.

在这次演讲中，我将介绍智能SANDs（快速分析纳米光流体诊断系统），以预测和阻止传染病的传播。智能SANDs指的是由三个主要部分组成的先进分子诊断系统：自包含的芯片上样本制备和液体活检过程，用于DNA、RNA和蛋白质生物标志物的超快等离子体放大方法，以及智能手机光学系统接口。此外，纳米等离子体光学天线允许通过量子生物电子转移（QBET）成像来检测活细胞中线粒体细胞色素c中的电子转移（ET）动态。活细胞中ET的无创实时QBET光谱成像可以开启生命科学的新时代，因为它捕捉了活细胞中的时空ET动态。纳米等离子体光学天线还可以捕捉细菌外泌体（EVs）的秘密通信代码，以更好地理解细菌通信、致病机制和耐药性。

我还将讨论人类外泌体如何成为诊断和治疗的新范式，以及基于外泌体的EXODUS（通过超快速纯化系统检测外泌体）应用的最新进展。由于EXODUS通过谐振器产生高速、纯度和产量，通过自动化无标记的外泌体纯化系统从各种生物流体中分离外泌体，它提供了最敏感的液体活检检测（来自血液、眼泪、尿液或唾液）。例如，从癌症患者的尿液样本中显著改进的外泌体纯化使我们能够获得高效的多组学数据，并比较肾脏和膀胱癌的富集途径。我们还开发了iTEARS（通过快速分离系统整合泪液外泌体分析），以识别蛋白质和miRNA的生物标志物，并在一滴眼泪中看到疾病的世界。基于EXODUS的iTEARS可以提供一种解决方案，以识别包括传染病、神经退行性疾病和癌症在内的许多其他疾病。

对于个性化精准纳米医学，我将介绍带有量子生物传感器和线粒体电子传递链的治疗调节的脑类器官MAP（微生理分析平台）的开发。基于人类诱导多能干细胞的脑类器官MAP为解决神经病理学的基本原理问题和寻找神经退行性疾病的解决方案提供了理想的模型。此外，来自患者的脑类器官可以再现患者的反应，并帮助个性化医疗。智能SANDs、QBET、EXODUS和脑类器官MAP将通过生物学、化学、物理学和工程学的融合，影响定量生命科学和精准纳米医学。
