Title: Seokhyeon Baek and Metal Oxide Thin-Film Transistor Biosensing

Introduction

Seokhyeon Baek is an inventor associated with Suwon-si, South Korea, and the Ajou University Industry-Academic Cooperation Foundation. His listed patent focuses on a semiconductor-based DNA sensor designed to detect target DNA through hybridization.

Latest Patents

Baek is credited with 1 patent: “Biosensor Based on Metal Oxide Thin Film Transistor and Manufacturing Method for the Same.” The invention describes a sensor with two spaced electrodes and a channel layer between them. A target-coupling layer on the channel carries probe DNA that detects target DNA through a hybridization reaction. A passivation layer selectively exposes part of the target-coupling layer, while a gate layer may be positioned beneath or above the substrate, or above the target-coupling layer. The channel layer includes a metal oxide and a carbon nanotube.

Career Highlights

The patent reflects Baek’s work in biosensor technology, semiconductor devices, and DNA detection. The disclosed design combines a metal-oxide thin-film transistor structure with carbon nanotubes and DNA-based target recognition.

Collaborations

Baek’s listed coworkers include Sungjun Park and Chuljin Hwang. The patent is associated with the Ajou University Industry-Academic Cooperation Foundation.

Conclusion

Seokhyeon Baek’s patent presents a semiconductor-based approach to DNA sensing that integrates transistor components, a carbon-nanotube-containing channel, and probe DNA for target detection.
