“…Detection time was approximately 30 min, and the sensor was demonstrated to be regenerable using 0.01 M hydrochloric acid. Another SPR biosensor for the detection of BPA was demonstrated by Matsumoto's group . Their sensor also used inhibition detection format and BPA−OVA conjugate immobilized on the sensor surface by physical adsorption.…”

“…The sensor was shown to be able to detect BAP at 1 ng/mL (1 ppb) levels. 334 Imato's group developed an SPR biosensor for the detection of 2,4-dichlorophenol based on competitive detection format. 333 They used the commercial SPR sensor SPR-20 functionalized with monoclonal antibodies against 2,4dichlorophenol immobilized on the sensor surface via gold binding peptide and protein G. Detection was based on the competition between the analyte present in sample and added BSA-2,4-dichlorophenol conjugate.…”

“…17 Optical-based surface plasmon resonance biosensors were also successfully employed for bisphenol A detection and their efficiency to be used for real sample analysis was shown with wastewater. Although typical detection limits of SPR biosensors for bisphenol A are around 1 ng mL −1 , 32,33 the researchers estimated the LOD as 0.08 and 0.14 ng mL −1 in PBS and wastewater, respectively, using antibody-based affinity arrays that require covalent immobilization of the receptors onto the surface as well as surface modification. 34 Other biosensing platforms based on the application of aptamers with fluorescent biosensors have been recently reported with their detection limits reaching very low ng mL −1 levels.…”

The paper describes a novel dip-and-gauge hand-held sensor device for the rapid, cost-effective, and on-site detection of bisphenol A and arsenic in drinking water samples. Different working electrode diameters ranging from 1.5 mm to 4 mm were designed and fabricated to construct a new electrochemical biosensor. The sensor was employed for the chronoamperometric detection of bisphenol A and voltammetric determination of arsenic in drinking water samples. Bisphenol A measurements resulted in a detection limit of 10 ng mL −1 with a linear range of 0-4000 ng mL −1. Baby products and bottles have to be completely free of bisphenol and hence a liquid-phase microextraction method has been developed to reduce the detection limit further to 0.6 ng mL −1. Arsenic detection was investigated in the concentration range of 0.4-250 ng mL −1 with a detection limit of 1.9 ng mL −1. The current study showed that the designed electrode array allows low detection limits (below threshold levels), although a bare gold surface is used for the study. Hence, together with a hand-held sensor device that works by simply dipping the sensor chip into a water container, this cost effective system has the potential to be used either by household consumers or for on-site inspection purposes.
