The document discusses the application of nanotechnology in biosensors. It begins by defining nanotechnology and biosensors. Nanoparticles are gaining interest in biosensing applications due to their size-dependent properties. Standard procedures for detection are time-consuming, non-specific, costly, and require trained personnel. Nanoparticles can be used to develop micro/nanobiosensors that are fast, inexpensive, simple to use, efficient, and portable. Various types of nanoparticles and detection techniques using nanoparticles like fluorescence, inductively coupled plasma mass spectrometry, and potentiometric analysis are then described.

This paper depicts a new configuration for modular hybrid power conversion systems, namely, multi-hybrid generation system (MHGS), and parallel connection at the output, such that the converter of each unit shares the load current equally. This is a significant step towards realizing a modular power conversion system architecture, where smaller units can be connected in any series/parallel grouping to realize any required unit specifications. The supercapacitor (SC) as a complementary source is used to compensate for the slow transient response of the fuel cell (FC) as a main power source. It assists the Fe to meet the grid power demand in order to achieve a better performance and dynamic behavior. Reliable control of the proposed MHGS with multiple units is also a challenging issue. In this paper, a simple control method to achieve active sharing of load current among MHGS modules is proposed. The simulation results verify the performance of the proposed structure and control scheme.

A presentation on 'Biosensors in Food Industry'. This presentation is the my work of status paper report on the same topic. Bio sensors usage in food industry and its prospects. The presentation is mostly pictorial but give a good idea about present scenario of usage of bio sensors in food industry in India with special focus on dairy and agriculture.
a device that converts the chemical energy from a fuel into electricity through a chemical reaction with oxygen or another oxidizing agent - from MSE-HUST k54
Biosensors are based on use of biological material as the sensing element which reacts or interacts with the analyte resulting in a detectable chemical or physical change.
Applications of nanotechnology in food packaging and food safetyDr. IRSHAD A

Over the past few decades the evolution of a number of science disciplines and technologies have revolutionized food and processing sector. Most notable among these are biotechnology, information technology etcā¦ and recently nanotechnology which is now constantly growing in the field of food production, processing, packaging, preservation, and development of functional foods. Food packaging is considered as one of the earliest commercial application of nanotechnology in food sector. Around more than 400 Nanopackaging products are available for commercial use. In 2008, nanotechnology demanded over $15 billion in worldwide research and development money (public and private) and employed over 400,000 researchers across the globe (Roco, M. C. et al. 2010). Nanotechnologies are projected to impact at least $3 trillion across the global economy by 2020, and nanotechnology industries worldwide may require at least 6 million workers to support them by the end of the decade (Roco, M. C. et al. 2010). Scientists and industry stakeholders have already identified potential uses of nanotechnology in virtually every segment of the food industry from agriculture (e.g., pesticide, fertilizer or vaccine delivery; animal and plant pathogen detection; and targeted genetic engineering) to food processing (e.g., encapsulation of flavor or odor enhancers; food textural or quality improvement; new gelation or viscosifying agents) to food packaging (e.g., pathogen, gas or abuse sensors; anticounterfeiting devices, UV-protection, and stronger, more impermeable polymer films) to nutrient supplements (e.g., nutraceuticals with higher stability and bioavailability). Undeniably, the most active area of food nanoscience research and development is packaging: the global nano-enabled food and beverage packaging market was 4.13 billion US dollars in 2008 and has been projected to grow to 7.3 billion by 2014, representing an annual growth rate of 11.65% (www.innoresearch.net).This is likely connected to the fact that the public has been shown in some studies to be more willing to embrace nanotechnology in āout of foodā applications than those where nanoparticles are directly added to foods.
