• Fast, definitive detection of MRSA and other pathogens at point of care
• Avoid safety issues while minimizing patient and staff exposure
• Eliminate unnecessary preventive treatment with antibiotics
Identification
Separation
Detection
Amplification
Sample Prep • Build more complex
systems
• ‘Stack’ modules to form a more capable instruments
• Design task specific instruments
• Scalable => single use and high throughput formats use similar technology
• Process complexity for individual modules the same • Processes/materials can be
optimized at each level • Molding can reduce the cost
of modules/components • LSU is a leader in developing
technology for polymer, modular microfluidic systems
Modular Microfluidics for Pathogen Identification
