pDEP-RACS (Positive Dielectrophoresis-induced Deterministic Lateral Displacement-based Raman-Activated Cell Sorting) is an advanced method for isolating and analyzing single cells, particularly useful in microbiology and biomedical research.
Key Features:
-Integrated Technology: pDEP-DLD-RACS combines positive dielectrophoresis (pDEP), deterministic lateral displacement (DLD), and Raman-Activated Cell Sorting (RACS) for high-throughput, label-free cell screening and sorting based on metabolic phenotypes.
-pDEP: Manipulates cells based on their dielectric properties, driving them towards specific microfluidic channels.
-DLD: Uses microstructures to filter and sort cells by size, enabling physical separation of cells within a microfluidic device.
-RACS: Analyzes the molecular composition of cells using Raman spectroscopy, allowing identification and sorting based on unique molecular fingerprints.
Advantages:
-High-Throughput: Capable of processing cells at a high rate, suitable for large-scale studies and clinical applications.
-Label-Free Analysis: Does not require fluorescent labels or markers, preserving the natural state of cells.
-Precision Sorting: Sorts cells based on size, metabolic activity, and molecular composition.
pDEP-RACS represents a convergence of microfluidics, dielectrophoresis, and Raman spectroscopy, offering a powerful tool for cellular analysis with broad implications for biological research and clinical diagnostics.
