Yadoung S, Xu H, Dokuta S, Jeeno P, Yana P, Thongkham M, et al.
Foods . 2025 Mar; 14(5). PMID: 40077521
Ciprofloxacin is metabolized from enrofloxacin for use in poultry to manage respiratory and gastrointestinal diseases, raising concerns due to its widespread tissue distribution and prolonged systemic persistence. This lateral flow...

Ishimatsu R
Anal Sci . 2025 Feb; PMID: 39998808
In this mini-review, recent progress in electrogenerated chemiluminescence (ECL) reported by our group is mainly introduced. First, the general principles of ECL and standard molecules for ECL are described, and...

Heliyon . 2023 Nov; 9(11):e21722. PMID: 38027909
We demonstrate that dopamine can be used as a reagent for colorimetric enzyme-linked immunosorbent assay (ELISA) using horseradish peroxidase (HRP). Dopamine was able to be polymerized in the presence of...

Ishimatsu R, Tashiro S, Nakano K
J Phys Chem B . 2023 Oct; 127(43):9346-9355. PMID: 37857283
Electrogenerated chemiluminescence (ECL) is a light emission phenomenon caused by electrochemically generated radical anions (R) and cations (R), in which the ion annihilation results in the formation of a pair...

Angew Chem Int Ed Engl . 2023 Mar; 62(21):e202301109. PMID: 36878874
This study reports an effective peripheral decoration of organic donor-acceptor diads with B(C F ) for stabilizing electrogenerated radical ions. By employing a common p-type organic semiconductor benzothienobenzothiophene (BTBT) as...

Antibiotics (Basel) . 2022 Nov; 11(11). PMID: 36358166
Fluoroquinolones (FQs) are among the antibiotics whose widespread use in farm-raised animals results in potentially harmful residues in the end products. Additionally, most Thai farmers use antibiotics. Amoxicillin and enrofloxacin...

Talanta . 2020 Aug; 218:121102. PMID: 32797869
A flow enzyme-linked immunosorbent assay (ELISA) method based on light absorption by enzymatically generated aniline oligomer in the presence of horseradish peroxidase (HRP), HO, and aniline is proposed. Aniline oligomer...

Langmuir . 2020 Aug; 36(34):10166-10174. PMID: 32787041
A hyperbranched polymer (HBP) made of three-way junction (TWJ) DNAs is reported. Three types of 26-mer DNAs with 5'-ends modified with psoralen (PSN) were synthesized. All had self-complementary sequences starting...
