Organs-on-chips (OoCs) are systems containing engineered or natural miniature tissues grown inside microfluidic chips. To better mimic human physiology, the chips designed to control cell microenvironments and maintain tissue-specific functions. Combining advances in tissue engineering microfabrication, OoCs have gained interest as a next-generation experimental platform investigate pathophysiology effect of therapeutics body. There many examples there applications, making it difficult for...

Abstract Simultaneous detection of multiple analytes from a single sample (multiplexing), particularly when done at the point need, can guide complex decision-making without increasing required volume or cost per test. Despite recent advances, multiplexed analyte sensing still typically faces critical limitation measuring only one type molecule (e.g., small molecules nucleic acids) assay platform. Here, we address this bottleneck with customizable platform that integrates cell-free...

Intestinal organoids are 3D cell structures that replicate some aspects of organ function and organized with a polarized epithelium facing central lumen. To enable more applications, new technologies needed to access the luminal cavity apical surface organoids. We developed perfusion system utilizing double-barrel glass capillary pressure-based pump modify contents human intestinal organoid for extended periods time while applying cyclic cellular strain. Cyclic injection withdrawal...

Abstract Simultaneous detection of multiple analytes from a single sample (multiplexing), particularly when at the point need, can guide complex decision-making without increasing required volume or cost per test. Despite recent advances, multiplexing still typically faces critical limitation measuring only one type molecule assay platform – for example, small molecules nucleic acids. In this work, we address bottleneck with customizable that integrates cell-free expression (CFE)...

<h3>Background</h3> Protein-protein interaction (PPI) is one of the many mechanisms where individual cells understand and modulate surrounding environment through communication with nearby or extracellular matrix. In diseases including cancer, some PPIs have been identified to adversely impact immune response. One well-known example between programmed cell death ligand 1 (PD-L1) protein (PD-1). Tumor utilize PD-1/PD-L1 evade activities. While immunotherapies targeting blockade approved by...

To mimic physiological microenvironments in organ-on-a-chip systems, physiologically relevant parameters are required to precisely access drug metabolism. Oxygen level is a critical microenvironmental parameter maintain cellular or tissue functions and modulate their behaviors. Current setups oftentimes subjected the ambient incubator oxygen at 21%, which higher than most if not all concentrations. Additionally, each different ranging from 0.5 13%. Here, closed-loop modular...

Abstract Understanding tissue heterogeneity is critical for elucidating cell-cell interactions with important implications in immuno-oncology, inflammation, and neuroscience. Tissue poses immense challenges to understanding underlying molecular mechanisms using techniques such as qRT-PCR or bulk sequencing. While single-cell RNA sequencing can provide information about precise cellular composition of tissues, data analysis be cumbersome spatial context lost. With platforms RNAscope, target...

<h3>Background</h3> Tumor cells employ multiple tactics to evade immune cell activities. Programmed death ligand 1 (PD-L1) is one of the key antigens presented on tumor that bind programmed protein (PD-1) and block response.
