  • Patent number: 11781104
    Abstract: The present invention provides an ultra-microinjection detection and control device based on lensless imaging and a method thereof. A lensless optical liquid level sensor is used to measure a change of a liquid level in an injection needle. A microinjection control unit is used to track the change of the liquid level and correct an injection pressure of the injection pump. Transmitted light generated by a parallel light source passes through a transparent glass tube of the injection needle. Then the transmitted light passes through a light filtering film to reduce the intensity of the parallel light source to a photosensitivity range of a micro linear array image sensor chip. Finally, the transmitted light enters the micro linear array image sensor chip, so that the micro linear array image sensor chip measures the change of the liquid level in the injection needle.

  • Patent number: 10494491
    Abstract: The present invention includes the efficient dispersion and high loading of fillers in a thermoplastic polymer matrix. In a first general embodiment, the present invention includes a method wherein fillers are first synthesized and dispersed in a liquid monomer. The liquid monomer is then polymerized to a solid. The nanofillers may be silver nanoparticle/nanowire fillers. Ethylene glycol may serve as a solvent, reducing agent as well as precursor monomer for polymerization. In a second general embodiment, the present invention includes a method wherein fillers may be separately synthesized (or obtained commercially) and then added and dispersed in a liquid monomer. The liquid monomer is then polymerized to a solid. In a third general embodiment, a composite is synthesized using interfacial polycondensation. This is accomplished by aggressive mixing of two solvents during the reaction. The aggressive mixing forms microdroplets (i.e.

  • Patent number: 6235504
    Abstract: Methods for identifying genetic sequences useful as genomic equivalent markers for organisms are described. The method involves determining the ratio of the absolute number of copies of wild type and mutant amplicons in a number of samples from organisms heterozygous for the mutation. After establishing the number of copies of a particular genetic sequence per genome, the sequence may be used as a measure of the number of genomes per sample, in order to normalize the analysis of another target sequence to abundance per cell. By way of example, the CCR5 gene was shown to be present at 2 copies per genome, and used to measure the number of copies per cell of HIV-1 provirions, human herpesvirus-8, and &agr; deletion circles, a measure of recent thymic emigrants for assessing immune reconstitution.
