Using this approach, we will confine P. aeruginosa bacteria tagged with mCherry, a fluorescent-protein-based reported, within 3D microstructures on the optical fiber tip. We will then expose the bacterial structure with an excitation source to create excited states promoting fluorescence, which we will detect using a photomultiplier tube (PMT). The fluorescence is an expression of mCherry, which gets activated…
In this proposal, we report the design of two bioanalytical sensors: (1) a fluorescence optrode-based optical fiber sensor and (2) a carbon-based optically transparent electrode. The first provides a means for spatially organizing microorganisms to monitor their social behavior in response to different chemical environments. The electrode sensor enables the detection of signaling molecules that are responsible for, or a consequence of, sociomicrobial behavior. Upon their completion, these…

called laser communication. It is wireless connections through the atmosphere. DVD players work with the use of a modem-like device called a transmission module. This converts digital signals to LED or laser light. This light then travels through a fiber optic cable to the destination…
Design of the modified optical sensor used with Equations 1 and 21. The power to integrate an optic fiber into fabrics was measured to determine whether the optic fibers broke during the integration process. Equation 3 was used for the power calculation in decibel-milliwatts (dBm) 1. dBm=10 log(P_transmitted/(1 mW)) [3] Integration of the fibers into fabric has been successful. The diameter of the fiber that has been developed is 1 millimeter thick. One challenge…
Aeronautical University November 9, 2014 Transmission medium of signal propagation and its impact on operational design. The three systems selected to discuss the different communication designs over different domains are: the BlueFin UUV using a tethered fiber-optic connection. the RQ-2b Pioneer drone using the Tadiran Spectra Link RF communication for LOS. the Mars Rover also using RF communication for BLOS. The three systems have different operational constraints with different mission…
and more homes and company are starting to replace their normal UTP cables with fiber optical cables. These optical fiber cables are thin strands of glass the size of a human hair. They are more reliable and the doesn’t lose packets and they travel at the speed of light. (Explainthatstuff, 2016) stated that a single strand of optical fiber can carry approximately 25,000 telephone calls and a bundle of the optical fiber can carry a million calls. Another type of network cable is the coaxial…
method I and the zincon method. However, all these methods are spectroscopic methods requiring costly and huge equipments and need proper sampling and storage [10]. They also have their limitations when concentration to be measured is in ppm level .Optical Fiber grating(OFG) sensors may provide a good option as a chemical sensor in determining the concentration of trace elements in drinking water. This method is simple, requires minimum equipments and most important, can be monitored on line so…
Diffuse Optical Tomography is non invasive, non ionizing functional imaging modality used for detection of brain tumor and breast cancer. A forward model design depicts the placement of laser source and photo-detector around the tissue boundary. The light propagation on the phantom takes place in Near-Infra-Red wavelength. The incident light on the tissue boundary was absorbed and scattered. The scattered rays are detected by the photo-detector and scattered voltage of the tissue was measured.…
allow us to establish the connection. While most internet participants have hear of dial-up, Modem, ISDN and fiber connections an even faster connection is near. The new technology, known as next-generation passive optical network, or NG-PON2 is being tested. So what is the difference between a fiber connections to the home, which a small percentage has, to the NG-PON2? The NG-PON2 fiber is able to utilize four separate colors of light allowing for the operation of the internet connection to be…
