“…Later, it was modified by different researchers and adapted for their specific purposes [2][3][4][5][6]. Now, the bacterial bioluminescent assay is a traditional and important biotechnological application of the bioluminescence phenomenon [7][8][9][10][11]. The tested physiological parameter here is luminescence intensity that can be easily measured instrumentally.…”

Effects of Americium-241 (241Am), alpha-emitting radionuclide of high specific radioactivity, and tritium (3H), beta-emitting radionuclide, on luminous bacteria Photobacterium phosphoreum were compared. Bioluminescence intensity served as a marker of bacterial physiological activity. Three successive stages in the bioluminescence response to 241Am and 3H were found under conditions of lowdose irradiation: (1) absence of effects, (2) activation, and (3) inhibition. They were interpreted in terms of bacterial response to stressfactor as stress recognition, adaptive response/syndrome, and suppression of physiological function (i.e. radiation toxicity). Times of bioluminescence activation (TBA) and inhibition (TBI) were suggested as parameters to characterize hormesis and toxic stages in a course of chronic low-dose irradiation of the microorganisms. Values of TBA and TBI of 241Am were shorter than those of 3H, revealing higher impact of alpha-irradiation (as compared to beta-irradiation) under comparable radiation doses. Increases of peroxide concentration and NADH oxidation rates in 241Am aquatic solutions were demonstrated; these were not found in tritiated water. The results reveal a biological role of reactive oxygen species generated in water solutions as secondary products of the radioactive decay. The study provides a scientific basis for elaboration of bioluminescence-based assay to monitor radiotoxicity of alpha- and beta-emitting radionuclides in aquatic solutions.

“…The technologies used to increase the storage time and to ensure the safe consumption of highly perishable products, such as meat, have undergone a continuous evolution over the time [13][14][15]. Besides, the difusion of active packaging, systems capable of interacting dynamically with the food and/or with the atmosphere in order to save the healthiness of the product and to extend its shelf life, is increasing [16].…”

Urgent need of increased food production and availability are crucial in humankind future. A key aspect concerns the food preservation, wherein packaging is a main aspect. Packaging is still in a primitive form, utilized as a way to separate food from environmental conditions, not considering the inside situation. Improvement of packaging means less cost, more food available, and waste decrease. Several solutions are emerging to face this challenge. They are focused on three aspects: the antimicrobial agent; the packaging material; and the technological implication in the inal production of packaging. Biotechnology is expected to play a central role in the future food to solve central points, as retain integrity and actively prevent food spoilage. In this phase, several projects are moving, still waiting to converge in adequate products. The galaxy of smart packaging is rapidly moving and increasing in researches. This phase represents a chaotic period of several proposals production and tentative in solving the food preservative problems, using new technologies and advanced techniques, like nanotechnology. Waiting the collapse into a central paradigm, it is interesting and useful to follow the scenario of researches on smart packaging based on natural products here reported.

“…At its most basic, a biosensor can be described as having a sensing element for selective detection of target and a method to transduce the interaction as a measureable signal (Thakur & Ragavan, 2013).…”

“…The main advantage with electrochemical transduction is the simplified design, sensitivity and amenable to miniaturization (Arugula & Simonian, 2014). Optical transduction is regarded as sensitive equal to or greater than electrochemical although has the disadvantage of needing camera/detectors for quantitative measurements (Thakur & Ragavan, 2013). Yet, because most sensors are qualitative many rely on visual inspection to assess a positive or negative tests result.…”

Highlights•Background to the evolution of biosensor based on nanoparticles.•Application of nanoparticles in biosensor devices.•Overview of biosensor formats applied in food testing.•Examples of integrated biosensor systems for food sampling.•Prospects and challenges in nanosensors in pathogen testing.The following will provide an overview on how advances in nanoparticle technology have contributed towards developing biosensors to screen for safety and quality markers associated with foods. The novel properties of nanoparticles will be described and how such characteristics have been exploited in sensor design will be provided. All the biosensor formats were initially developed for the health care sector to meet the demand for point-of-care diagnostics. As a consequence, research has been directed towards miniaturization thereby reducing the sample volume to nanolitres. However, the needs of the food sector are very different which may ultimately limit commercial application of nanoparticle based nanosensors. IntroductionThrough evolution we have developed senses to enable us to differentiate good foods from bad. The art of cheese making, brewing and viticulture has relied on the producer using their senses to assess quality. Establishing if a food was safe was more problematic and typically relied on tasters to ensure dishes provided to their masters were sound. Clearly, analytical testing is a more reliable and objective means of assessing the quality and safety of foods. Laboratory testing provided a basis for developing protocols and limits that could be applied to foods to define quality or safety. Yet, the expense and delay in acquiring results remain critical limitations. Consequently, there is an on-going demand for biosensors that can be used outside the laboratory environment to assess the safety and quality of foods on-site.In many instances the needs of the food industry mirrored that of the health sector where rapid diagnostics would enhance treatments and prognosis. The health sector provides a more lucrative market for diagnostic companies so it is not unexpected to find that the majority of research to date has been towards developing biosensors to meet the market demands. Consequently, those biosensors encountered in the food sector are derived from those devices initially fabricated to meet the needs of the health care sector. Within this context, the following review provides a brief history on how the field of biosensors developed and the contribution made by advances in nanoparticle technology. The efforts in transferring biosensor technologies to the food sector will be provided with a focus on safety, and to a degree, quality assessment. The review does not attempt to provide an exhaustive list of advances given the numerous quality reviews are already published in this area (Arugula and Simonian,
