Summary: Biosensors are important analytical devices, and aptamers as a new biorecognition element play a significant role in them. Aptamers are short sequences of DNA, RNA, and peptides with high affinity similar to antibodies. Aptasensors with immobilized aptamers serve as an alternative to biosensors based on antibodies and other bioreceptor molecules.

Summary: Investigating the interactions between small, charged molecules and aptamers using surface plasmon resonance (SPR) is challenging due to low small molecule response and nonspecific electrostatic interactions. However, aptamers are increasingly used in sensors for small molecule detection, and a simple, direct SPR assay would greatly benefit sensor development. This study presents a method using streptavidin-biotin capture and a high-ionic-strength buffer to characterize the interaction between serotonin and an aptamer with SPR. Other methods, such as immobilization and thiol-coupling, were also investigated for comparison.

Summary: By taking advantage of target-assisted electrochemically mediated atom transfer radical polymerization (teATRP) for signal amplification, a simple and cost-effective electrochemical aptasensor is developed for sensitive and selective detection of low-abundance endotoxin. The aptamer receptor selectively captures endotoxin, and signal amplification is achieved through the dual amplification strategy of ATRP-initiated polymer chain grafting. This aptasensor shows high sensitivity with a detection limit of 1.2 fg/mL and has great potential for detecting low-abundance endotoxin and other glycan chain containing bio-targets.

Summary: A facile amperometric biosensor was developed using a Co/2Fe metal-organic framework (MOF) with oxidase mimicking properties for the detection of sialic acid (SA). The biosensor was constructed by immobilizing Co/2Fe MOF and N-acetylneuraminic Acid Aldolase (NANA-Aldolase) enzyme on a gold screen-printed electrode. The sensor showed a linear range of 0.02 mM-1.00 mM for SA concentration and a limit of detection of 0.026 mM. The developed biosensor was successfully applied for the detection of SA in GD3 ganglioside and HeLa cancer cell lines, providing a more practical and accurate system.
