  • Patent number: 10744504
    Abstract: A microscale sampling device including a frame is provided in the present invention, a sample container, a communicating channel and a resistance channel are defined in the frame. At least one sampling chamber is defined in the communicating channel. An end of the communicating channel is communicated with the sample container and the communicating channel is arranged below the sample container. An end of the resistance channel is communicated with the sampling chamber, and the other end of the resistance channel is communicated to an output joint. The resistance channel is shaped with at least one discontinuous shape change.

  • Publication number: 20200009526
    Abstract: A semiconductor quantum dot is provided with a non-metallic substrate, and has a particle size ranged from 0.3 to 100 nm. A method of carrying out a chemical reaction or a photoluminescence reaction by using the semiconductor quantum dot is also provided. A redox reaction of a target sample is carried out, an active substance is generated, or an electron-hole pair is produced from the semiconductor quantum dot by providing the semiconductor quantum dot with a predetermined energy. Photons are released by the combination of the electron-hole pair so as to perform the photoluminescence reaction.
