A Changeable Lab-on-a-Chip Detector for Marine Nonindigenous Microorganisms in Ship’s Ballast Water

摘要: The spread and invasion of many nonindigenous species in the ship’s ballast water around world has been a hazard threat to ecology, economy, human health. rapid accurate detection marine invasive is essential. This article aimed at analysing quality by means changeable microfluidic chip detector thus comply with D-2 standard management sediment convention. system was designed through integration technology, impedance pulse sensing LED light induced chlorophyll fluorescence (LED-LICF) detection. can measure number, size, shape, volume targeted microorganisms, it also determine intensity, which an important factor activity phytoplankton. samples were Chlorella volutis, Dunaliella salina, Platymonas subcordiformis, Chrysophytes, Escherichia coli, Enterococci. whole or operation be accomplished online few minutes using micron sample solution. valid data outputs are simultaneously displayed terms both amplitudes fluorescent intensity signals. for multi-sizes real time changing microchannel sizes on chip. Because successfully detect label-free applicable in-situ detections some modifications system.
