Choi W, Shin S, Do J, Son J, Kim K, Lee J
Micromachines (Basel)
. 2024 May;
15(5).
PMID: 38793194
We investigated the impact of surface treatments on Si-based electrolyte-gated transistors (EGTs) for detecting urea. Three types of EGTs were fabricated with distinct gate electrodes (Ag, Au, Pt) using a...

Shin S, Kim S, Choi W, Do J, Son J, Kim K, et al.
Biosensors (Basel)
. 2024 Mar;
14(3).
PMID: 38534231
The sensing responses of SARS-CoV-2 spike protein using top-down-fabricated Si-based electrolyte-gated transistors (EGTs) have been investigated. An aptamer was employed as a receptor for the SARS-CoV-2 spike protein. The EGT...

Sybodies as Novel Bioreceptors toward Field-Effect Transistor-Based Detection of SARS-CoV-2 Antigens
Zhang C, Parichenko A, Choi W, Shin S, Panes-Ruiz L, Belyaev D, et al.
ACS Appl Mater Interfaces
. 2023 Aug;
15(34):40191-40200.
PMID: 37603713
The SARS-CoV-2 pandemic has increased the demand for low-cost, portable, and rapid biosensors, driving huge research efforts toward new nanomaterial-based approaches with high sensitivity. Many of them employ antibodies as...

Choi W, Jin B, Shin S, Do J, Son J, Kim K, et al.
Biosensors (Basel)
. 2023 May;
13(5).
PMID: 37232926
We experimentally demonstrate Si-based electrolyte-gated transistors (EGTs) for detecting urea. The top-down-fabricated device exhibited excellent intrinsic characteristics, including a low subthreshold swing () (~80 mV/dec) and a high on/off current...

Biosensors (Basel)
. 2022 Jan;
12(1).
PMID: 35049652
The highly sensitive detection of peanut allergens (PAs) using silicon-based electrolyte-gated transistors (Si-EGTs) was demonstrated. The Si-EGT was made using a top-down technique. The fabricated Si-EGT showed excellent intrinsic electrical...

Sensors (Basel)
. 2018 Nov;
18(11).
PMID: 30424510
We report the electrical characteristics and pH responses of a Si-nanonet ion-sensitive field-effect transistor with ultra-thin parylene-H as a gate sensing membrane. The fabricated device shows excellent DC characteristics: a...
