Patent number: 11517904Abstract: Provided is a digital microfluidic device for quick polymerase chain reaction. The digital microfluidic device includes an enclosed chamber for holding droplets comprising PCR mixtures. The chamber has an upper layer and a lower layer, which provide a top heater and a bottom heater contained in a thermal electrode respectively to form dual heaters. The lower layer further has an array of electrodes and a dielectric layer, e.g. Norland Optical adhesive 61, coating thereon. Such arrangement of the digital microfluidic device allows quick and homogeneous heating of droplets to lower the heating voltage, shorten the reaction time, and prevent the dielectric layer from breakdown during the thermal cycle.Type: GrantFiled: May 20, 2019Date of Patent: December 6, 2022Assignee: University of MacauInventors: Yanwei Jia, Liang Wan, Cheng Dong, Haoran Li, Tianlan Chen, Pui-In Mak, Rui Paulo da Silva Martins

Publication number: 20200362400Abstract: The present disclosure discloses an enhancing agent and a kit for enhancing nucleic acid amplification reaction and a method for performing nucleic acid amplification reaction, relating to the field of biotechnology. The enhancing agent disclosed in the present disclosure has a domain capable of binding to fluorescent dye and a quenching group for quenching fluorescence emitted by the fluorescent dye bound to the domain binds. As the binding affinity between the above domain and the fluorescent dye is lower than the binding affinity between a target amplification product of nucleic acid amplification reaction and the fluorescent dye, the enhancing agent not only can reduce inhibition of high-concentration fluorescent dye to amplification reaction, but also can enhance signal intensity of the fluorescent dye in the nucleic acid amplification reaction based on microfluidic chip, improving reliability of application of the fluorescent dye as amplification indicator on the microfluidic chip.Type: ApplicationFiled: February 17, 2020Publication date: November 19, 2020Inventors: Yanwei Jia, Ren Shen, Pui-In Mak, Rui Paulo da Silva Martins
