TL;DR: This paper is a very small report about optical biosensor and its development and importance in various fields.
Abstract: The dimension of biomolecules is of few nanometers, so the biomolecular devices ought to be of that range so a better understanding about the performance of the electronic biomolecular devices can be obtained at nanoscale. Development of optical biomolecular device is a new move towards revolution of nano-bioelectronics. Optical biosensor is one of such nano-biomolecular devices that has a potential to pave a new dimension of research and device fabrication in the field of optical and biomedical fields. This paper is a very small report about optical biosensor and its development and importance in various fields.

TL;DR: The principles, characteristics, and applications of recent rapid detection methods for foodborne pathogens, including nucleic-acid-based methods, immunological methods, and biosensor- based methods are reviewed.
Abstract: Food safety is increasingly becoming an important public health issue, as foodborne diseases present a widespread and growing public health problem in both developed and developing countries. The rapid and precise monitoring and detection of foodborne pathogens are some of the most effective ways to control and prevent human foodborne infections. Traditional microbiological detection and identification methods for foodborne pathogens are well known to be time consuming and laborious as they are increasingly being perceived as insufficient to meet the demands of rapid food testing. Recently, various kinds of rapid detection, identification, and monitoring methods have been developed for foodborne pathogens, including nucleic-acid-based methods, immunological methods, and biosensor-based methods, etc. This article reviews the principles, characteristics, and applications of recent rapid detection methods for foodborne pathogens.

TL;DR: An overview on recent important achievements in breast screening methods and breast biomarkers along with biosensors for rapidly diagnosing breast cancer along with microwave imaging techniques is provided.
Abstract: Early-stage cancer detection could reduce breast cancer death rates significantly in the long-term. The most critical point for best prognosis is to identify early-stage cancer cells. Investigators have studied many breast diagnostic approaches, including mammography, magnetic resonance imaging, ultrasound, computerized tomography, positron emission tomography and biopsy. However, these techniques have some limitations such as being expensive, time consuming and not suitable for young women. Developing a high-sensitive and rapid early-stage breast cancer diagnostic method is urgent. In recent years, investigators have paid their attention in the development of biosensors to detect breast cancer using different biomarkers. Apart from biosensors and biomarkers, microwave imaging techniques have also been intensely studied as a promising diagnostic tool for rapid and cost-effective early-stage breast cancer detection. This paper aims to provide an overview on recent important achievements in breast screening methods (particularly on microwave imaging) and breast biomarkers along with biosensors for rapidly diagnosing breast cancer.

TL;DR: In this paper, the application of beneficial physico-chemical properties of ZnO nanostructures for the detection of wide range of biological compounds is highlighted for medical diagnostics require accurate, fast and inexpensive biosensors, the advantages inherent optical methods of detection are considered.
Abstract: This review article highlights the application of beneficial physico-chemical properties of ZnO nanostructures for the detection of wide range of biological compounds. As the medical diagnostics require accurate, fast and inexpensive biosensors, the advantages inherent optical methods of detection are considered. The crucial points of the immobilization process, responsible for biosensor performance (biomolecule adsorption, surface properties, surface defects role, surface functionalization etc.) along with the interaction mechanism between biomolecules and ZnO are disclosed. The latest achievements in surface plasmon resonance (SPR), surface enhanced Raman spectroscopy (SERS) and photoluminescence based biosensors along with novel trends in the development of ZnO biosensor platform are presented.

TL;DR: This study focuses on the concise classification, underlying principles on the optical transducer, optical (surface) analytical techniques as a part of biosensing and use of nanostructures in optical sensors, and the recent advances in label-free optical biosensors based on the target analytes.
Abstract: Safety of food is a scientific domain requiring advanced handling, preparation, and storage. Food is a paramount need for growth of microorganisms it serves as a medium for proliferation and contamination. The primary historical techniques for food analysis are time-consuming and laborious whereas biosensors have an easier control over these limitations. Biosensor technology is a powerful tool for food analysis. Optical sensors reveal higher calibre for analysis of drugs, pesticide residues, pathogens, heavy metals, toxic substances as well as for overall hygiene monitoring in the food system. Label-free operations altogether acquired a well-established need for the characterization and identification of molecular components. We review the recent advances in label-free optical biosensors based on the target analytes. This study focuses on the concise classification, underlying principles on the optical transducer, optical (surface) analytical techniques as a part of biosensing and use of nanostructures in optical sensors. The main highlights include characterisation of localized surface plasmon and surface plasmon resonance based biosensors. Additionally, other optical biosensors such as bioluminescent optical fibre biosensors, evanescent wave fluorescence, ellipsometric, surface-enhanced Raman scattering and light-addressable potentiometric sensors are also well explained and characterized for food and environmental applications.
