We present a Pulsed Laser Activated Cell Sorter (PLACS) integrated with 3D sheathless inertial focusing that is capable to sort at 10,000 particles sec−1 with >90% sort purity and 6,000 cells sec−1 with >80% sort purity. It is realized by exciting laser induced cavitation bubbles in a single layer PDMS microfluidic channel to create high speed liquid jets to deflect detected fluorescent samples...
We report a 3D PDMS microfluidic pulsed laser triggered fluorescence activated cell sorter capable of sorting at 11,000 cells sec−1 with >95% purity or at 45,000 cells sec−1 with 45% purity within a single channel.
We report a high speed microfluidic fluorescence activated cell sorter (μFACS) capable of sorting at a throughput of 3000 beads/sec and 560 cells/sec with >90% sample purity and 90% cell viability after sorting. The sorting mechanism is realized by exciting dynamic vapor bubbles with focused laser pulses in a microfluidic PDMS channel. The explosive bubble expansion generates fast fluid flows which...
We report a high speed fluorescence activated microfluidic switch capable of achieving a switching time of 50 μsec with a detection efficiency of 86.6% and a switching efficiency of 86.5% at a particle flow speed of ~0.7 m/s. The switching mechanism is realized by exciting dynamic vapor bubbles with focused laser pulses in a microfluidic PDMS channel. The explosive bubble expansion generates fast...
Rhodamine B (Rh B) has been grafted into the channels of rod-like mesoporous silica SBA-15, which had been modified by organic silane with terminal amino group in CHCl 3 solvent. The investigations of UV–vis, photoluminescence, and FT-IR confirmed the existence of Rh B in the channels of RSBA-15 (rod-like SBA-15). The composites show strong fluorescence and obvious blue-shift at the yellow...
