Importantly, trends and developments of this interaction found in both biosensors and bioassays have opened new perspectives in the sensing field and are therefore also of great interest to the sensor community. (i) Biosensors are chemical sensors in which the recognition system utilizes a biochemical mechanism for the interaction process in/at the recognition layer. [Extracted from the article]

They can be produced in different formats and the most widely applied ones include the scFv and Fab fragments as well as single domain antibodies (sdAbs) obtained from heavy-chain antibodies from camelids (VHH), also known as nanobodies, or from sharks, referred to as variable new antigen receptor (VNAR) single domain antibodies [[6]]. These single-stranded DNA (ssDNA) or RNA molecules possess a well-defined 3D structure that binds with high affinity to their "complementary" species. Traditionally, biological receptors such as antibodies, enzymes, nucleic acids, or receptor proteins have been successfully applied to this aim. Peptides selected from combinatorial or phage display libraires, or designed in silico, have also been used as alternatives to natural antibodies, especially for sensor development, although to a much lower extent than rAbs, aptamers, and MIPs [[13]].

A bisphenol A (BPA) molecularly imprinted polymer, the composition of which was optimised using a chemometric approach, has been applied to the selective preconcentration of the template from aqueous samples. The selectivity of the polymer toward BPA and related compounds was evaluated chromatographically. The BPA-imprinted polymer was packed in a column and used for continuous on-column solid-phase extraction (MISPE) of aqueous samples followed by subsequent analysis by HPLC with fluorescence detection of the eluted fractions. The composition of the washing solvent applied in the MISPE procedure was optimised to favour the specific interactions of the MIP with BPA find to remove the non-selectively bound matrix components. The MISPE method has proven to be effective for selective preconcentration of BPA in aqueous samples (recoveries >84% obtained in the eluate for 10– 100 mL sample volumes) enabling detection and quantification limits of 1.0 and 3.3 ng mL-1, respectively (based on 25 mL sample size). Analytical recoveries were between 92 and 101% for river water samples spiked with known amounts of BPA (30, 60, and 80 ng mL-1): relative standard deviations (RSD) were lower than 5.0%.
