  • In this study, we developed a micropattern technology in the shape of RFID TAG antenna using ultrasonic micropattern manufacturing system developed to enable micropattern technology. The ultrasonic tool horn in longitudinal vibration mode was installed in the micropattern manufacturing system to develop the ultrasonic press technology for the micropattern antenna shape of the RFID TAG antenna shape on the insulating sheet surface. The ultrasonic shaping technology was manufactured by applying the resonance design technique to a 60kHz tool horn, and by using the micropattern manufacturing system, the coil wire having a thickness of 25㎛ can be ultrasonically press-molded on an insulating sheet of 200㎛ or less. In ultrasonic press technology, the antenna shape having a minimum line width of 150㎛ could be molded without disconnection, peeling, or twisting of the coil wire.

  • An antibody layer was fabricated to detect Escherichia coli O157:H7. The micropattern of 16-mercaptohexadecanoic acid (16-MHDA) as alkylthiolate was formed on the gold surface by using the PDMS stamp with microcontact printing $({\mu}CP)$ techniques. In order to form antibody patterns on the template, protein G was chemically bound to the 16-MHDA patterns, and antibody was adsorbed on a self-assembled protein G layer. The formation of the 16-MHDA micropattern, self-assembled protein G layer and antibody pattern on Au substrate was confirmed by surface plasmon resonance (SPR) spectroscopy. Finally, the micropatterning method was applied to fabricate the antibody probe for detection of E. coli O157:H7, and monitoring of antigen by using this probe was successfully achieved.
