Patents by Inventor Heung Chuan Lam

Heung Chuan Lam has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11110461
    Abstract: The present disclosure provides fully integrated microfluidic systems to perform nucleic acid analysis. These processes include sample collection, nucleic acid extraction and purification, amplification, sequencing, and separation and detection. The present disclosure also provides optical detection systems and methods for separation and detection of biological molecules. In particular, the various aspects of the invention enable the simultaneous separation and detection of a plurality of biological molecules, typically fluorescent dye-labeled nucleic acids, within one or a plurality of microfluidic chambers or channels. The nucleic acids can be labeled with at least 6 dyes, each having a unique peak emission wavelength. The present systems and methods are particularly useful for DNA fragment sizing applications such as human identification by genetic fingerprinting and DNA sequencing applications such as clinical diagnostics.

  • Patent number: 11052398
    Abstract: Plastic electrophoresis separation chips are provided comprising a plurality of microfluidic channels and a detection window, where the detection window comprises a thin plastic; and the detection window comprises a detection region of each microfluidic channel. Such chips can be bonded to a support provided an aperture is provided in the support to allow detection of samples in the electrophoresis chip at the thin plastic detection window. Further, methods for electrophoretically separating and detecting a plurality of samples on the plastic electrophoresis separation chip are described.

  • Publication number: 20200070173
    Abstract: A fast, multiplexed PCR system is described that can rapidly generate amplified nucleic acid products, for example, a full STR profile, from a target nucleic acid. Such systems include, for example, microfluidic biochips and a custom built thermal cycler, which are also described. The resulting STR profiles can satisfy forensic guidelines for signal strength, inter-loci peak height balance, heterozygous peak height ratio, incomplete non-template nucleotide addition, and stutter.
