  • Publication number: 20230038558
    Abstract: A method for determining the integrity of at least one complex based on at least one biological sample and at least one matrix, including at least the following steps:—acquiring at least one image,—analyzing the image sent by extracting light intensity values representative of at least one spectral band,—relating the light intensity values to one another to obtain representative spectral data,—determining a state of integrity of the complex by comparing each of the representative spectral data by similarity grouping with a determined similarity threshold,—triggering at least one first alert, by the analysis unit, when the representative data are similar to the first state of integrity or to the second state of integrity.

  • Publication number: 20210079441
    Abstract: The invention relates to a method for detecting the Gram type and the fermenting character of a bacterial strain, said method comprising: illuminating, in the wavelength range of 390 nm to 900 nm, at least one bacterium from said strain which has a natural electromagnetic response within said range; acquiring, within said range, a light intensity reflected by, or transmitted through, said illuminated bacterium; and determining the Gram type and the fermenting character of the bacterial strain according to the light intensity acquired within said range.

  • Publication number: 20060019333
    Abstract: The present disclosure generally relates to chemical, biological, and/or biochemical reactor chips and/or reaction systems such as microreactor systems, as well as methods for constructing and using such systems. In some cases, humidity control materials are utilized to provide beneficially high rates of gas exchange. The humidity control materials may be used, in certain instances, to provide at least adequate, and in certain embodiments superior, gas exchange for systems having small volumes. In some cases, the currently disclosed materials include certain polymers, e.g., poly(acetylene)s such as poly(alkylacetylene)s. The polymers may be at least partially halogenated (for example, fluorinated) in some instances. In certain embodiments, a chip and/or a reaction system may be constructed so as to promote cell growth within it. In some embodiments, the chips may include one or more reaction sites. The reaction sites can be very small, for example, with a volume of less than about 1 ml.
