“…Although the use of different SPR configurations for multianalyte measurements has been described (Chinowsky et al, 2007;Dostálek et al, 2007;Homola et al, 2005;Kawazumi et al, 2005;Kim et al, 2007;Mauriz et al, 2007;Trevino et al, 2009;Yang and Kang, 2008), to our knowledge, this is the first time that a portable multiplexed SPR immunosensor has been reported for multiple antibiotic residue detection in milk samples. An SPR imaging has been reported to detect several antibiotic families have been detected.…”

“…Matrix interferences are known to limit the suitability of SPR technology to analysis of clinical samples [63,64]. Nevertheless, SPR technology has been used for detecting analytes from saliva [63,65,66], urine, and serum [64], and it can be used in multianalyte assays [67,68]. Traditional SPR devices are expensive [69], but by using mass-producible grating couplers instead of prism couplers, the production costs can be significantly lowered.…”

Simple and inexpensive yet sensitive and robust diagnostic tests are critically needed for resource-poor settings to enable timely diagnosis and effective use of limited health care resources. Current tests are often too expensive, too slow, or have compromised clinical performance, and they often require health care professional to perform the test. In addition, most assays are not intended to be used in extreme environmental conditions, but their performance may be affected by high temperatures and humidity often encountered in resource-poor settings. This review provides an overview of current immunoassay technologies and their advantages and limitations with respect to their feasibility to resourcepoor settings. Future trends of immunoassay development for decentralized testing are also discussed. Homogeneous assays as such are out of the scope of this article because they are generally not yet sensitive enough or otherwise less feasible for inexpensive rapid diagnostic tests.

“…By immobilization of the molecularly imprinted nanoparticles onto the SPR chip it was easy to detect iron regulating hormone Hepcidin-25 [47]. Other modified SPR sensors were employed to detect testosterone [48,49], gonadotropic hormones and luteinizing hormone [50], pituitary hormones such as human thyroid-stimulating, growth, follicle-stimulating [51], and insulin [52]. There are other reviews and articles that focus on the importance and the application of SPR biosensors for the diagnosis of medically important entities such as viruses, neurotransmitters, proteins, hormones, nucleic acids, cells, drugs, and disease biomarkers [53][54][55][56][57].…”

For a healthy life, the human biological system should work in order. Scheduled lifestyle and lack of nutrients usually lead to fluctuations in the biological entities levels such as neurotransmitters (NTs), proteins, and hormones, which in turns put the human health in risk. Dopamine (DA) is an extremely important catecholamine NT distributed in the central nervous system. Its level in the body controls the function of human metabolism, central nervous, renal, hormonal, and cardiovascular systems. It is closely related to the major domains of human cognition, feeling, and human desires, as well as learning. Several neurological disorders such as schizophrenia and Parkinson’s disease are related to the extreme abnormalities in DA levels. Therefore, the development of an accurate, effective, and highly sensitive method for rapid determination of DA concentrations is desired. Up to now, different methods have been reported for DA detection such as electrochemical strategies, high-performance liquid chromatography, colorimetry, and capillary electrophoresis mass spectrometry. However, most of them have some limitations. Surface plasmon resonance (SPR) spectroscopy was widely used in biosensing. However, its use to detect NTs is still growing and has fascinated impressive attention of the scientific community. The focus in this concise review paper will be on the principle of SPR sensors and its operation mechanism, the factors that affect the sensor performance. The efficiency of SPR biosensors to detect several clinically related analytes will be mentioned. DA functions in the human body will be explained. Additionally, this review will cover the incorporation of nanomaterials into SPR biosensors and its potential for DA sensing with mention to its advantages and disadvantages.
