“…Food safety and clinical methods for identification of B. cereus group strains do not distinguish between B. cereus and B. thuringiensis, another member of the Bacillus genus. 74 Pathogenic Bacillus species have been detected using antibodies, 35,36,59,[75][76][77][78][79][80] DNA probes, 81,82 bacteriophages, [83][84][85] and mammalian cells 86,87 as the recognition element with several different types of transducers including fluorescent array, 33,35,36,59 evanescent wave fiber-optic, 77 laser cytometry, 86,87 electrochemical, 75,76,[78][79][80][81][82] and mass sensitive sensors. [83][84][85]88,89 Tims and Lim developed a fiber-optic biosensor capable of detecting B. anthracis spores in common powders at concentrations of 3.2 Â 10 5 spores per mg or higher within an hour.…”

Biosensors are of great significance because of their capability to resolve a potentially large number of analytical problems and challenges in very diverse areas such as defense, homeland security, agriculture and food safety, environmental monitoring, medicine, pharmacology, industry, etc. The expanding role of biosensing in society and a real-world environment has led to an exponential growth of the R&D efforts around the world. The world market for biosensor devices, according to Global Industry Analysts, Inc., is expected to reach $12 billion by 2015. Such expedient growth is driven by several factors including medical and health problems, such as a growing population with a high risk of diabetes and obesity, and the rising incidence of chronic diseases such as heart disease, stroke, cancer, chronic respiratory diseases, tuberculosis, etc.; significant problems with environmental monitoring; and of course serious challenges in security and military applications and agriculture/food safety. A review paper in the biosensor technology area may be structured based on (i) the principles of detection, such as the type of transducer platform, bioanalytical principles (affinity or kinetic), and biorecognition elements origin/properties (i.e. antibodies, enzymes, cells, aptamers, etc.), and (ii) the application area. This review follows the latter strategy and focuses on the applications. This allows discussion on how different sensing strategies are brought to bear on the same problem and highlights advantages/disadvantages of these sensing strategies. Given the broad range of biosensor related applications, several particularly relevant areas of application were selected for review: biological threat agents, chemical threat agents, and medicine.

Context:Diarrhea is a common disease across the world. According to WHO, every year about two billion cases of diarrhea are reported in the world. It occurs mainly in the tropical regions and is a main cause of morbidity and mortality, particularly in young children and adults.Evidence Acquisition:One of the major causes of diarrheal diseases is bacteria; detection of pathogenic bacteria is a global key to the prevention and identification of food-borne diseases and enteric infections (like diarrhea).Conclusions:Therefore, development of rapid diagnostic methods with suitable sensitivity and specificity is very important about this infectious disease. In this review, we will discuss some of the important diagnostic methods.

Abstract:In recent years, food storage environment safety has been a major concern for food and health scientists. There is growing interest in electrochemical biosensors due to their high sensitivity and rapid response. The aim of this review article is to provide details regarding the development of enzyme-based electrochemical biosensors, and their use in the detection of a range of chemical and biological compounds in the food industry. We have focused on the basic principle, generation, classification, and application of electrochemical biosensors for food safety.
