TL;DR: A modified selection method based on target-induced release of strands was used to isolate aptamers of Cd (II) with high specificity to develop a facile, cost-effective and quick-testing light-up biosensor with excellent specificity for cadmium ions detection.

TL;DR: By replacing the sensing element, i.e., the aptamer of VEGF used in this work, more biosensors for sensitive detection of other biomarkers proteins can be fabricated based on the strategy proposed in this study.

TL;DR: In this paper, a sandwich SPR sensor is constructed by using thrombin as a model analyte, which can be used to improve the sensitivity and selectivity of SPR biosensors in protein detection and disease diagnosis.

TL;DR: Investigation of antibody surface coverage and antibody layer thickness utilizing surface plasmon resonance (SPR) on the ProLinker™, a well-known protein artificial receptor molecule, revealed that antibodies were vertically immobilized in a dense monolayer when directly immobilized on theProLinker SAM in an orientation comparable to that of protein G immediate antibody immobilization.

TL;DR: In this article, a self-assembled monolayer of calix[4]crown-5 derivatives was used for the detection of K + ion using a modified gold chip based on surface plasmon resonance (SPR).
