“…The gold surface of the SPR chip was modified with an allyl mercaptan in previous articles [ 23 ]. The SPR chip was cleaned with a piranha solution (3:1 concentrated H 2 SO 4 :H 2 O 2 , v / v ) and then washed with ethanol–water mixture.…”

“…One of the advantages of SPR sensors is thanks to their sensitive refractive index changing during the surface binding, giving the results simultaneously and label free. SPR sensors are used in various fields for food quality control analysis [ 20 , 21 ], environmental analysis [ 22 ] and diagnostic purposes in medicine [ 23 , 24 , 25 , 26 ].…”

In this study, we designed a simple, rapid, sensitive and selective surface plasmon resonance (SPR) sensor for detection of L-phenylalaine by utilizing molecular imprinting technology. l-phenylalanine imprinted and non-imprinted poly(2-hydroxyethyl methacrylate-methacryloyl-l-phenylalanine) polymeric films were synthesized onto SPR chip surfaces using ultraviolet polymerization. l-phenyalanine imprinted and non-imprinted SPR sensors were characterized by using contact angle, atomic force microscopy and ellipsometry. After characterization studies, kinetic studies were carried out in the concentration range of 5.0–400.0 μM. The limit of detection and quantification were obtained as 0.0085 and 0.0285 μM, respectively. The response time for the test including equilibration, adsorption and desorption was approximately 9 min. The selectivity studies of the l-phenylalanine imprinted SPR sensor was performed in the presence of d-phenylalanine and l-tryptophan. Validation studies were carried out via enzyme-linked immunosorbent analysis technique in order to demonstrate the applicability and superiority of the l-phenylalanine imprinted SPR sensor.

“…The development of a highly sensitive portable SPR biosensor is amongst the promising detection platforms that provide on-site biosensing at a high level of portability and cost-effectiveness. [20][21][22] Furthermore, the ability to perform simultaneous assays rapidly allows the use of the instrument for point-of-care applications where multiple parameters are desired to be monitored. [23][24][25] Consequently, the integration of MIMs with the SPR system has been made excellent improvements in sensing technology.…”

In this study, the fibrinogen imprinted surface plasmon resonance (SPR) biosensor was developed for the monitoring of fibrinogen levels in patient serum samples using a microcontact imprinting method. The fibrinogen imprinted and nonimprinted polymeric films on the SPR chip surface were prepared by the microcontact imprinting approach and characterized by ellipsometer, contact angle measurements, and Fourier transform infrared spectroscopy. The limit of detection and quantification values of the fibrinogen imprinted SPR biosensors in the linear range of 0.05-9.0 mg/mL were 0.00066 and 0.00219 mg/mL, respectively. In all kinetic ana-lyzes, the response time was 11 min for equilibration, adsorption, and desorption cycles. The selectivity studies of SPR biosensors were performed in the presence of fibrinogen, myoglobin, hemoglobin, and immunoglobulin G in a competitive manner. For the validation studies of the fibrinogen imprinted SPR biosensor, the fibrinogen level of diluted patient serum samples was determined by enzyme-linked immunosorbent assay (ELISA). The experimental results show that the serum samples of patients in high and low-risk groups were identified with the recovery of about % 97-99 according to both SPR biosensor and ELISA analysis results.

“…Both sensor techniques are easy to use, affordable, sensitive, selective, and their response time is short (Justino, Freitas, Pereira, Duarte, & Rocha, 2015; Laricchia‐Robbio & Revoltella, 2004; Piletsky & Turner, 2002). SPR and QCM sensors have been used for pharmaceutical analysis, food safety measurements, and environmental monitoring in previous studies (Bakhshpour, Özgür, Bereli, & Denizli, 2017; Çimen & Denizli, 2020; Feng, Li, Jian, Shen, & Yu, 2007; Jalilzadeh, Çimen, Özgür, Esen, & Denizli, 2019; Kartal, Çimen, Bereli, & Denizli, 2019; Saylan et al., 2017).…”

In this study, surface plasmon resonance (SPR) and quartz crystal microbalance (QCM) sensors were prepared for the detection of amoxicillin from the commercial and local chicken eggs by using molecular imprinting technique. Amoxicillin imprinted poly(hydroxyethyl methacrylate-methacrylic acid) polymeric film was synthesized onto the surface of the SPR and QCM chips by ultra violet polymerization to determine lower concentrations of amoxicillin. Ellipsometry, contact angle analysis, and atomic force microscopy measurements were used for the surface morphology of the polymeric film layer. The ellipsometric thickness of AMOX imprinted and nonimprinted SPR and QCM chip surfaces were measured as 35 ± 0.9 nm, 32.89 ± 1.9 nm, 30 ± 0.6 nm, and 28 ± 0.22 nm, respectively. Contact angles of bare gold surfaces, AMOX imprinted SPR and QCM chip surfaces were measured to be as 82.3°± 0.15, 79.2°± 0.14, 75.01°± 1.07, and 69.11°± 0.89, respectively. The range of linearity was measured as 0.1 to 10 ng/mL for amoxicillin imprinted SPR and QCM sensors. The maximum residue limit of AMOX in eggs is at 10 μg/kg in accordance with the "Positive List System for Agricultural Chemical Residues in Foods." The response time for the test, including adsorption, desorption, and regeneration, was approximately 45 min. The limit of detections for SPR and QCM sensors were found to be 0.0005 and 0.0023 ng/mL, respectively. The reusabilities of amoxicillin imprinted SPR and QCM sensors were observed by the equilibration-binding-regeneration. Validation studies of the AMOX imprinted SPR and QCM sensors were performed by liquid chromatography-tandem mass spectrometry.
