Study Notes
Microfluidic Devices: Lab-on-a-Chip
Definition
- A lab-on-a-chip (LOC) is a type of microfluidic device that integrates multiple laboratory functions on a single chip.
- It is a miniaturized device that performs various laboratory tasks, such as chemical reactions, separations, and detections, on a small scale.
Key Features
- Small size: typically on the order of millimeters or centimeters
- Low sample volume: often in the range of microliters or nanoliters
- High surface-to-volume ratio: enables efficient heat transfer and chemical reactions
- Integration of multiple functions: allows for automation and miniaturization of laboratory processes
Advantages
- Reduced sample consumption: minimizes waste and conserves valuable samples
- Increased speed: enables faster analysis and detection
- Improved accuracy: reduces human error and increases precision
- Portability: enables point-of-care testing and field deployments
Applications
- Clinical diagnostics: disease detection, monitoring, and diagnosis
- Biotechnology: DNA analysis, protein analysis, and cell manipulation
- Pharmaceutical research: high-throughput screening, drug discovery, and development
- Environmental monitoring: water quality analysis, pollutant detection, and monitoring
Components
- Microchannels: narrow channels for fluid flow and mixing
- Microchambers: small compartments for chemical reactions and detections
- Micropumps: small pumps for fluid manipulation and control
- Sensors: integrated sensors for detecting physical, chemical, or biological parameters
Fabrication Techniques
- Photolithography: uses light to pattern materials on a surface
- Soft lithography: uses elastomeric materials to create microstructures
- 3D printing: uses layer-by-layer deposition to create complex structures
- Micro-molding: uses molds to create microstructures with high accuracy and precision
