  • Patent number: 10421793
    Abstract: The present invention relates to a proton-transport vesicle and a method for preparing the same, the proton-transfer vesicle comprising: (a) a single phospholipid bilayer liposome; (b) a rhodopsin protein; and (c) a photosystem II protein, wherein the rhodopsin protein and the photosystem II protein are inserted and located in a bilayer of the liposome. Since the heterologous photosensitive proteins are inserted and located in the bilayer of the liposome, the vesicle has an absorption wavelength band of the whole region of visible light by utilizing absorption bands of different lights of the respective photosensitive proteins. Thus, the restricted efficiency caused by utilizing only a specific wavelength in existing organisms or artificial vesicles was improved, and the wavelength region can be enlarged to the all wavelength ranges of visible light.

  • Patent number: 10201811
    Abstract: The present invention relates to a method for manufacturing a module type microfluidic chip comprising: (a) printing electrode patterns on a substrate using a conductive ink and inkjet printing; (b) cutting the printed electrode patterns; and (c) assembling the cut electrode patterns to manufacture the module type microfluidic paper chip. Unlike the traditional method for manufacturing printed circuit substrate using a patterning agent or device, the method of the present invention only incorporates a simple printing process using an inkjet printer, and thus patterning can be simplified and various types of chips can be manufactured depending on the assembly type of electrode patterns. Accordingly, inexpensive, economical, and highly utilizable microfluidic chips can be provided using the method of the present invention.
