Welcome to iBMF Lab @ CUA
The Integrated BioMicroFluidics (iBMF) Lab, directed by Associate Professor Xiaolong Luo in the Department of Mechanical Engineering, School of Engineering at the Catholic University of America (CUA), aims to develop novel microscale platforms that bridge engineering and biology. We handle fluids on a microscale (microfluidics), develop bio-microsystems with novel fabrication strategies (biofabrication), and diagnose biological events with microscopic and biosensing techniques. We use biopolymers, including polysaccharides extracted from crab/insect shells (chitosan), seaweed algae (alginate), and proteins (collagen) to construct 3D hydrogels, fabricate freestanding membranes, establish bilayer lipid membranes, assemble biomolecules, immobilize living cells, and entrap optically-active nanoparticles in microfluidic networks. We design and fabricate integrated bio-microsystems to understand fundamental science and address practical challenges. Novel bio-microsystems developed in our lab find critical applications in protein/metabolic engineering, membrane biology, cell-cell communications, and microbiome in synthetic ecosystems, realizing laboratory functions in microsystems (Lab-on-a-Chip) to expedite novel drug discovery and improve human health.
