We present a rapid and stain-free quantitative viral plaque assay using lensfree holographic imaging deep learning. This cost-effective, compact, automated device significantly reduces the incubation time needed for traditional assays while preserving their advantages over other virus quantification methods. captures ~0.32 Giga-pixel/hour phase information of objects per test well, covering an area ~30x30 mm^2, in label-free manner, eliminating staining entirely. demonstrated success this...
Large language models (LLMs) are artificial intelligence (AI) platforms capable of analyzing and mimicking natural processing. Leveraging deep learning, LLM capabilities have been advanced significantly, giving rise to generative chatbots such as Generative Pre‐trained Transformer (GPT). GPT‐1 was initially released by OpenAI in 2018. ChatGPT's release 2022 marked a global record speed technology uptake, attracting more than 100 million users two months. Consequently, the utility LLMs fields...
Successful integration of point-of-care testing (POCT) into clinical settings requires improved assay sensitivity and precision to match laboratory standards. Here, we show how innovations in amplified biosensing, imaging, data processing, coupled with deep learning, can help improve POCT. To demonstrate the performance our approach, present a rapid cost-effective paper-based high-sensitivity vertical flow (hs-VFA) for quantitative measurement cardiac troponin I (cTnI), biomarker widely used...
Gram staining has been a frequently used protocol in microbiology. It is vulnerable to artifacts due to, e.g., operator errors and chemical variations. Here, we introduce virtual of label-free bacteria using trained neural network that digitally transforms dark-field images unstained into their Gram-stained equivalents matching bright-field image contrast. After one-time training, the model processes an axial stack microscopy (never seen before) rapidly generate staining, bypassing several...
Democratizing biomarker testing at the point-of-care requires innovations that match laboratory-grade sensitivity and precision in an accessible format. Here, high-sensitivity detection of cardiac troponin I (cTnI) is demonstrated through chemiluminescence-based sensing, imaging, deep learning-driven analysis. This chemiluminescence vertical flow assay (CL-VFA) enables rapid, low-cost, precise quantification cTnI, a key protein for assessing heart muscle damage myocardial infarction. The...
Beta-hemolytic, Group A Streptococcus pyogenes (GAS) is a life-threating pathogen and the reason for prominent disease, pharyngitis. The conventional analysis of GAS, gold standard, takes 48 hours related rapid tests lack in accuracy sensitivity. In this study, firstly, efficiency swab sampling, which must GAS detection, was discussed with proposed surface-enhanced Raman spectroscopy (SERS)-based batch assay each step controlled by plate-counting method. Secondly, SERS-based lateral flow...
The rapid spread of SARS-CoV-2 caused the COVID-19 pandemic and accelerated vaccine development to prevent virus control disease. Given sustained high infectivity evolution SARS-CoV-2, there is an ongoing interest in developing serology tests monitor population-level immunity. To address this critical need, we designed a paper-based multiplexed vertical flow assay (xVFA) using five structural proteins detecting IgG IgM antibodies changes immunity levels. Our platform not only tracked...
