While patient-derived organoids more accurately preserve tumor pathophysiology, their clinical translation is impeded by technical challenges related to standardization, reproducibility, and high-throughput compatibility. In this study, we developed a microfluidic-engineered platform that employed a laminin-enhanced decellularized small intestinal submucosa extracellular matrix (dSISML) to produce uniform organoid-laden microspheres (MP). This biohybrid system eliminated the need for tumor-derived matrices (e.g. Matrigel) and provided a physiologically relevant microenvironment. When integrated with microfluidics, the platform facilitated rapid and scalable production of size-tunable MP, thereby effectively addressing critical bottlenecks in organoid handling and drug testing workflows. Our study demonstrated that dSISML could sustain organoid growth and drug responsiveness comparable to Matrigel, while offering improved operational simplicity and reduced batch variability. Moreover, dSISML enabled simpler and controllable high-throughput microsphere preparation.

We developed dual-labelled hydrogel/scaffold composites for real-time monitoring of scaffold degradation in response to cell activity. Gelatin methacryloyl (GelMA) hydrogels are extensively explored for cartilage tissue engineering, albeit concerns remain regarding their mechanical properties under load-bearing conditions. To address this, a Hydrogel/Scaffold composite system was employed in this study, where a poly (ε-caprolactone) (PCL) hex prism edge structure acts as a scaffold supports of the cell-laden GelMA hydrogel. Fluorophore labelling of GelMA and PCL facilitated non-invasive monitoring of the Hydrogel/Scaffold composite biodegradation under cell proliferation conditions. Initially, the behaviour of fluorescent-tagged Hydrogel/Scaffold was examined under accelerated degradation conditions. Subsequently, human adipose-derived mesenchymal stem cells (hADSCs) loaded into fluorescent-labelled hydrogel/scaffolds were evaluated for their biocompatibility potential and chondrogenesis. Results demonstrated a correlation between the loss of fluorescence from Hydrogel/Scaffold degradation, accompanied by extracellular matrix accumulation. The fluorescently labelled hydrogel/scaffold holds promising application for cartilage tissue engineering, offering the capability to monitor biodegradation using high-throughput and contactless techniques.

This innovative approach systematically interrogates the intricate roles of matrix stiffness (spanning healthy and fibrotic conditions), extracellular matrix (ECM) composition, and protein concentration, while simultaneously examining their interdependent interactions. By leveraging DoE principles, we were able to explore 117 unique microenvironments on a single microscope slide, ultimately generating a comprehensive dataset of 234 different microenvironments without compromising statistical rigor. Our enhanced screening system enabled the identification of unique microenvironmental interactions critically significant in dictating cellular responses, including adhesion, survival, proliferation, epithelial-to-mesenchymal transition, and drug resistance markers. Utilizing advanced statistical techniques such as linear models and principal component analysis, we characterized phenotypic clusters defined by precise microenvironmental cues. This work presents a robust, high-throughput microarray screening system that comprehensively explores the contributions of 9 physiologically relevant extracellular matrix proteins and matrix stiffness in modulating cellular behavior and disease progression through a methodologically sophisticated and statistically sound approach.

However, existing wearable materials are hindered by limited chemical functionality, static sensing capabilities, and insufficient adaptability to dynamic physiological conditions, which restrict their current impact in precision medicine. Recent advancements have focused on integrating genetic engineering and synthetic biology into wearable platforms, resulting in genetically programmable biointerfaces that enhance specificity, responsiveness, and functional versatility in clinical and personalized healthcare settings. Current applications of these bioengineered devices include real-time monitoring of pathogens, hormones, therapeutic drug levels, and physiological behaviors, offering superior precision and adaptability compared to traditional wearable technologies. This review highlights two key engineering approaches driving this field: genetically modified living cells and cell-free synthetic biology systems. While promising, several challenges still limit broader clinical adoption, including biosafety concerns, the instability of biological components, and translational hurdles. Addressing these challenges requires progress in biocompatibility, controlled gene expression, and durable wearable materials. Looking ahead, future research should aim to integrate these biointerfaces with implantable and smart therapeutic systems, develop autonomous biosensors with self-regulatory functions, and further expand their use in personalized medicine and real-time disease management. By bridging genetic programming with wearable diagnostics, these innovations are laying the groundwork for next-generation biohybrid systems designed to advance precision healthcare.
