Nano‐Phase Separation and Analyte Binding in Aptasensors Investigated by Nano‐IR Spectroscopy

Small, EarlyView.
An atomic force microscopy ‐ infrared spectroscopy (AFM‐IR) study on the fabrication of an aptamer‐based biosensor revealed the formation of nanodomains rich in DNA aptamers and blocking polyethylene glycol (PEG) molecules. Single‐molecule spectroscopy of the analyte protein is also reported.

Dissociation Constant (Kd) Measurement for Small‐Molecule Binding Aptamers: Homogeneous Assay Methods and Critical Evaluations

Small Methods, EarlyView.
The characteristics of aptamer is most commonly represented by the dissociation constant (Kd), which is critical for aptamer optimization. Here, the assays used to evaluate Kd, including labeled and label‐free assays, are evaluated and suggestions are made to ensure that true values are obtained, while other methods are cautioned.
