  • Publication number: 20080310692
    Abstract: A system and method for identifying organisms by analysis of scattergrams of colonies is disclosed. cattergrams are obtained by culturing samples and illuminating the resultant colonies by a laser. The forward scattered light is imaged and subject to a feature extraction process. The feature vector may include Zernike or Chebyshev moments and may also include Harelick texture features. Feature vectors may be used to train a classification process using either supervised or unsupervised machine learning techniques. The classification process may be used to associate a colony phenotype with the genotype of the sample.

  • Patent number: 7306924
    Abstract: A method for collecting a microbiological substance utilizes a micro fabricated biochip having a collection chamber. A fluid sample containing a microbiological entity of interest is delivered to the collection chamber in the biochip. Then a non-uniform electric field is generated in the collection chamber, to retain the microbiological entity of interest in the collection chamber. The microbiological entity is retained through dielectrophoresis induced by the energization of the electrodes by a periodically applied, alternating current.

  • Publication number: 20010053535
    Abstract: A microscale biosensor for use in the detection of target biological substances including molecules and cells is a microfluidic system with integrated electronics, inlet-outlet ports and interface schemes, high sensitivity detection of pathogen specificity, and processing of biological materials at semiconductor interfaces. A fabrication process includes an all top-side processing for the formation of fluidic channels, planar fluidic interface ports, integrated metal electrodes for impedance measurements, and a glass cover sealing the non-planar topography of the chip using spin-on-glass as an intermediate bonding layer. Detection sensitivity is enhanced by small fluid volumes, use of a low-conductivity buffer, and electrical magnitude or phase measurements over a range of frequencies.
