An ingenious electrochemical aptasensor for detection of CYFRA 21-1 based on dual-output toehold mediated strand displacement reaction.

Bioelectrochemistry, 2022
Herein, a "signal-on" electrochemical aptasensor based on dual-output toehold mediated strand displacement reaction (TMSDR) was developed to detect cytokeratin fragment antigen 21-1 (CYFRA 21-1).

Predictive role of CYFRA 21-1 for S-1 monotherapy in non-small cell lung cancer patients.

Respiratory Investigation, 2022
BACKGROUND S-1, an oral fluoropyrimidine derivative, is widely used for the treatment of several solid tumors. However, there are no predictive markers for its effectiveness. METHODS We retrospectively screened 108 patients with advanced non-small cell

Copper doped terbium metal organic framework as emitter for sensitive electrochemiluminescence detection of CYFRA 21-1.

Talanta: The International Journal of Pure and Applied Analytical Chemistry, 2021
Lanthanide metal organic frameworks (L-MOFs) are emerging as promising electrochemiluminescence (ECL) emitters for bioanalysis. This work proposed a copper doped terbium MOF as a luminescent tag for construction of a "signal-on" ECL immunosensing method.
