Finally, the paper concludes with the challenges faced and possible future development of optical fiber protein biosensors for further study. DNA biosensors, which use nucleic acids as their biological receptors, detect proteins and non-macromolecular compounds that interact with certain DNA fragments known as DNA probes or DNA primers. Over the last two decades, surface plasmon resonance (SPR) based biosensors have emerged as important and useful tools due to their unique features for real-time and label-free detection of biomolecular interactions [62, 63]. As a library, NLM provides access to scientific literature. Furthermore; nanotechnology role in biosensors development by binding nanomaterials with biosensors depending on nanomaterials characteristics, in order to enhance the detection processes of biosensors by increasing the surface area for most contact with analytes and increasing the electrical or optical properties of transducers. However, conventional commercial SPR-based biosensors and experimental devices are often represented by instruments, which utilize Kretschmanns scheme of plasmon excitation [65]. At the current time, no major side effects have been discovered related to optogenetics. This is because transducers and other electronic components that comprise the biosensor device are mostly temperature sensitive and this can greatly influence their stability. In viral bioreceptors, sensing constituents are whole cells, peptides, nucleic acids, aptamers and antibodies which are the most common bioreceptors [16]. This is a very important attribute for a biosensor since most applications require a biosensor to measure a target analyte over wide concentration ranges [11, 22].

Kozma P., Kehl F., EhrentreichForster E., Stamm C., Bier F.F. The capability of the biosensor to meet this criteria relies on the transducer which is required to perform in a precise and accurate manner [11]. Optical biosensors are the most common analytical techniques which depend on visual phenomena for detection of biological element and the target analyte interaction that employ absorption, fluorescence, phosphorescence, Raman, refraction, and surface plasmon resonance (SPR). These type of biosensors form the most researched and reported biosensors based on biological receptors [37, 38].

The transducer surface may be gold, carbon, silicon or hydrogels by direct attachment, streptavidin/ biotin affinity or silanisation [16]. Federal government websites often end in .gov or .mil. Ideally, a biosensor should have the lowest detection limit, especially if it is to be used in medical applications where the target analyte might be present at very low concentrations [22]. An enzyme, known as glucose oxidase, is used as a biological receptor which binds glucose and converts it to gluconic acid in the presence of oxygen. Depending on the purpose, sensitive and selective methods are needed for both quantitative and qualitative determination of target analytes. Endo T., Kerman T., Nagatani K., Hiepa N.M., Kim D.K., Yonezawa Y. Electron microscopy, can also be used for viral imaging. The serological investigations for antibodies against viral antigens are less sensitive and could be non-specific. It works by potentiometric, amperometric, conductometric, polarographic, capacitive or piezoelectric ways [32,33]. An appropriate electronic circuit is necessary to make conversion of the measured quantity to an electrical signal [59].

Optical biosensors provide new analytical tools with reduced size as well as facilitate large-scale high-throughput sensitive screening of a wide range of samples for many different parameters. Several types of nanomaterials used for diagnosis and biosensing such as nanoparticles (NPs), nanocomposites, carbon nanotubes (CNTs), quantum dots (QDs) and graphene or graphene-based nanomaterials [41]. Selectivity is a very important feature especially in medical applications where the test sample or sample matrix, usually blood or urine, contains numerous molecules that are quite similar to the target analyte and compete for binding to the biological receptor [22, 30]. Nanotechnology has various applications in several areas, like coatings, sensors, optical communications, agriculture, food, electromechanical systems, electronics, and biomedical applications [36].

Also, biosensors have been developed to detect particular compounds in foods. Quality control remains a major part of food production and is responsible for the production of healthy food with a prolonged shelf life and also complies with regulations. Employing the right transducer will result in a device with increased sensitivity while the sensitivity is more likely to be compromised by the use of an ineffective transducer [33, 34]. The site is secure. Novel nanomaterials such as Ag NPs, Au NPs and quantum dots are the most commonly highlighted in optical transducers because of their plasmonic properties [29,30] plasmonic nanomaterials applications can be divided into two systems; plasmonic and non-plasmonic system. These are known to use antibodies, aptamers, nucleic acids and enzymes as biological receptors. Another group of biosensors based on a biological receptor is DNA biosensors. Mokhtarzadeh A., et al.

Optical Biosensors, Second Edition describes the principles of successful systems, examples of applications, and evaluates the advantages and deficiencies of each. Initially, the molecule of interest in the test sample binds or interacts specifically with the biological receptor, resulting in a physiological change. This feature determines the ability of the biosensor device to resist change in its performance over a period of time in response to interruptions arising from external factors. This process is known as immobilization. Rapid shell vial culture technique for detection of enteroviruses and adenoviruses in fecal specimens: comparison with conventional virus isolation method.

The target analyte involves viral antigenic part that may be whole virus, viral proteins (capsid proteins), viral nucleic acids (RNA or DNA genomes) or viral-specific antibodies. Sizes of Nanomaterials ranging between 1 and 100nm, this offers a large surface area to volume ratios. As technology advances, new methods that will result in the development of even better biosensors are emerging, and these seek to address all limitations associated with these devices. Lee T., et al. : 26240120021 supported by the Research & Development Operational Programme funded by the European Regional Development Fund (ERDF). In viral diagnosis, virus isolation is considered the gold standard and the most sensitive method, however it is laborious and work taking 37days. The catalytic group of biological receptors are used in devices intended for continuous monitoring of substances at millimolar or micromollar concentrations. Some of the subclasses under the types of biosensors will also be explained. This state is called plasmon which transmitted parallel to the surface of metal (platform) [29]. SPR technology has opened a new avenue for many important applications in the field of sensing due to their attractive sensing capabilities, light weight, compactness and easy implementation [64, 65, 66, 67]. The main challenge for further research and innovation in the field of optical biosensors is that the optical detection principle allows construction of sensitive, simple and cheap analytical devices with a wide variety of possible applications in portable biosensor systems for in situ screening and monitoring, for example, in personalized medicine, remote areas or in developing countries where the availability of inexpensive diagnostic tools could save many lives.
