Method and apparatus for detection of particles |
摘要 |
The invention includes a particle detection system that detects bioparticles in a sample utilizing a sensor device that receives photoacoustic signals from a sample. The invention includes a system for distinguishing biologically active particles from non-biologically active particles in a sample utilizing a transducer to receive a laser induced photoacoustic signal from the sample and a fluorescence detector to receive laser induced fluorescence. The invention includes a method of screening a sample for the presence of one or more particle types by subjecting a sample to laser light and measuring at least one photonic response and at least one acoustic response are measured from the sample to produce a sample composite data set which is compared to a signature data set from a control sample. The invention also includes methods for detecting a change in the particle composition within a test area.
