  • Patent number: 11567002
    Abstract: A system for the identification of micro-organisms includes an irradiation unit adapted to sequentially provide coherent electromagnetic radiation of one or more wavelengths along a common optical path. A holder is adapted to retain a substrate having a surface adapted for growth of a micro-organism colony. A beamsplitter is adapted to direct the coherent electromagnetic radiation from the common optical path towards the retained substrate. An imager is arranged opposite the beamsplitter from the retained substrate and is adapted to obtain images of backward-scattered light patterns from the micro-organism colony irradiated by the respective wavelengths of the directed coherent electromagnetic radiation. Some examples provide radiation of multiple wavelengths and include an imager arranged optically downstream of the retained substrate to obtain images of forward-scattered light patterns from the micro-organism colony irradiated by the wavelengths of radiation.

  • Patent number: 8787633
    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.

  • Publication number: 20140066363
    Abstract: A nanoparticle includes a carbohydrate carrier and a bacteriocin. A method for prolonging efficacy of a bacteriocin against a food pathogen includes providing the bacteriocin in a delivery system, and inhibiting the food pathogen by the bacteriocin. A duration of efficacy of the bacteriocin against the food pathogen when the bacteriocin is provided in the delivery system exceeds a duration of efficacy of the bacteriocin when the bacteriocin is provided without the delivery system.

  • Patent number: 7465560
    Abstract: A system and a method of detecting and characterizing a bacterial colony are presented in which the results are determined within about 48 hours. The bacterial colony is disposed on a substrate and placed between a laser and detector. Light from the laser impinges upon and is scattered by the bacterial colony. The forward scattered light is detected by an optical detector. The signal from the optical detector is analyzed by an analyzer and displayed or supplied to a storage medium for review. As different strains of bacteria possess unique forward scattering fingerprints, the particular strain may be identified.

  • 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: 20030036054
    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.
