Special Issue Information

Dear Colleagues,

Microfluidic bioseparation focuses on the separation and purification of biological target components from a biological sample, and it is usually integrated with a bioassay, which involves the detection and quantification of specific analytes in a sample using miniaturized fluidic devices and techniques. Microfluidic bioseparation techniques have become increasingly vital in the field of bioanalysis and biomedical research due to the several key advantages and applications they offer; they are able to miniaturize and integrate complex bioanalytical workflows into a single device, enhance the sensitivity and throughput, and reduce the analysis time and cost. They therefore enable automation and the performance of high-throughput bioassay with multifunctionality and versatility for point-of-care and field applications relevant to drug discovery, genomics, proteomics, and clinical diagnostics. This Special Issue aims to address the recent progress in microfluidic bioseparation and integrated bioassay, welcoming original research articles, technical notes, and review articles. We hope to provide a collection of high-quality papers and a comprehensive overview of the latest advancements in microfluidic bioseparation and bioassay.

The precise isolation of circulating tumor cells (CTCs) from blood samples is a potent tool for cancer diagnosis and clinical prognosis. However, CTCs are present in extremely low quantities in the bloodstream, posing a significant challenge to their isolation. In this study, we propose a non-contact acoustic micropillar array (AMPA) chip based on acoustic streaming for the flexible, label-free capture of cancer cells. Three shapes of micropillar array chips (circular, rhombus, and square) were fabricated. The acoustic streaming characteristics generated by the vibration of microstructures of different shapes are studied in depth by combining simulation and experiment. The critical parameters (voltage and flow rate) of the device were systematically investigated using microparticle experiments to optimize capture performance. Subsequently, the capture efficiencies of the three micropillar structures were experimentally evaluated using mouse whole blood samples containing cancer cells. The experimental results revealed that the rhombus microstructure was selected as the optimal shape, demonstrating high capture efficiency (93%) and cell activity (96%). Moreover, the reversibility of the acoustic streaming was harnessed for the flexible release and capture of cancer cells, facilitating optical detection and analysis. This work holds promise for applications in monitoring cancer metastasis, bio-detection, and beyond. Full article
