Nanosensor ppt (seminor topic ) download
A nanosensor probe carrying a laser beam (blue) penetrates a living cell to detect the presence of a product indicating that the cell has been exposed to a cancer-causing substance.
Nanosensors are any biological, chemical, or physical sensory points used to convey information about nanoparticles to the macroscopic world. Though humans have not yet been able to synthesize nanosensors, predictions for their use mainly include various medicinal purposes and as gateways to building other nanoproducts, such as computer chips that work at the nanoscale and nanorobots. Presently, there are several ways proposed to make nanosensors, including top-down lithography, bottom-up assembly, and molecular self-assembly. (Foster 2006:166)

We propose an exhibit highlighting force microscopy intended to complement other exhibits in the proposed nanotechnology exhibit space. As the small size of nanotechnology is a key feature, it would be natural for visitors to have questions regarding the imaging and manipulation of such tiny objects. We propose an exhibit to help answer those questions. |

The communication channels within such a Body Area Network (BAN) network can be either completely wire-based, wireless or a mixture of both. The network may have static or dynamic, single-path or multi-path routing algorithms with a flat or a hierarchical topology.

SENSING FOR DANGER
ABSTRACT:
PICTURE THIS SCENARIO: A terrorist carefully negotiates city streets, moving ever closer to his target, an air force base on the outskirts of town. In the rear of his van, a homemade bomb containing plutonium and high explosives waits for the signal to explode. As one of the “good guys,” you’ve received information that the attack is imminent, but your sources don’t know its timing, the direction from which the vehicle will come, or what route it will take. What can you do to detect, identify, and track the van and its contents so that you can prevent the attack?
The researchers are focusing on systems for detecting and tracking threats. The systems go by many names correlated sensor networks, wide-area tracking systems, sensor or network fabrics but the concept behind them is the same. Take a number of wireless sensors (for instance, seismic, magnetic, pressure, acoustic, nuclear, or particle-counting), tie them together with a communications network, develop a scheme for fusing the data (that is, converting the data into forms easily interpreted by users), and make the system easy to deploy.
