Research Interests

The Bio-analytical and Microfluidics research group at NMT primarily focuses on developing novel analytical and bio-analytical methods for environmental, biological, and chemical analysis. The on-going projects explore the development of microsphere and polymer monolith based bio-assemblies as reactive surfaces for target binding. These bio-assemblies will be utilized in disease diagnostics. In another approach, bio-reactive surfaces are integrated with microfluidic systems to create portable detection systems. Our group also involve in developing sound wave-based microfluidic bio-analytical systems. This includes the development of silicon and aluminum-based microfluidic systems for bacteria, viruses, mammalian cells, and micro and nano particle separation. Our group also has interests in developing microfluidic based techniques for the removal of toxic chemicals like Bis-phenol A and particulate matter like nano and microplastics in aqueous systems.
