Investigation of the recognition interaction between glycated hemoglobin and its aptamer by using surface plasmon resonance

Dapeng Sun et al.

Summary: The study found that factors like pH and salt concentration of the solution can greatly affect the formation of a complex between aptamers and HbA1c. The loop L1 structure in the aptamer may be crucial for recognizing glycated hemoglobin, and the optimal detection condition was pH 6.

An aptamer biosensor for CA125 quantification in human serum based on upconversion luminescence resonance energy transfer

Xiaojing Zhang et al.

Summary: CA125 is a widely used biomarker for early detection of ovarian cancer. A biosensor using near-infrared excitable upconversion nanoparticles and carbon dots was developed with high quenching efficiency. In the presence of CA125, the upconversion luminescence intensity increased linearly, with a detection limit of 9.0 x 10(-3) U.mL(-1).
