This research paper tells about sustained delivery of small molecular drug ciprofloxacin using hydroxyapatite hybrid poly (vinyl alcohol) nanocomposites. Hydroxyapatite - poly (vinyl alcohol) nanocomposites are used as a vehicle to carry drug, protein, implantable materials etc. In situ synthesized hydroxyapatite hybrid poly (vinyl alcohol) matrix was characterized using different characterization techniques like XRD, SEM and FTIR. Small molecular drug ciprofloxacin was loaded into hydroxyapatite hybrid poly (vinyl alcohol) nanocomposites. The morphology of drug free and drug loaded hydroxyapatite concoction poly (vinyl alcohol) nanocomposites is observed using SEM. In-vitro drug release is quantified using UV/VIS spectrophotometer.Keywords

Visually impaired find difficult to identify colors and person, the main objective of this project is to make them overcome these. An external camera is fitted with goggles for acquiring images. The acquired image is processed to obtain the required features such as colors in the case of audio colors or facial features in the case of personal identification. The obtained feature is encoded using MATLAB, then fed into LabVIEW through which speakers are connected to get the respective audio signals. The color presented to the camera is converted to corresponding sound. This will also be useful for the visually impaired to identify their friends and foes using face identification software which is implemented in here. This project is meant to describe light, by its frequency and intensity, in terms of an audible signal. However, the domain of the system here is limited only to primary and secondary colors. The complete software solution is implemented using LabVIEW and MATLAB.Keywords

A novel sensor approach based on measurement of changes in capacitance of an electrochemical cell produced during enzyme catalyzed formation of products is described. The electrochemical property such as capacitance of an electrolyte between electrochemical cell depends on its ionic compositions, in turn depends on the resulting ionic constituents caused by catalytic action of the enzyme. Generation of micromolar (μM) concentration of ionic species causes large changes in capacitance that is measurable in picofarad (pF) range in capacitive electrodes. Broad clinical analytical application of this technique is demonstrated in this report by application to diagnostically valued enzymes measurements like pyrophosphatases and phosphatases. Specific measurements of enzyme activities were achieved over the concentration range of 0.125 – 5.0 mM of respective substrates. The performance of the electrochemical sensor based enzyme biochemical assays were compared directly with identical assays employing spectrophotometric detection and found to match well.Keywords

Breast cancer is the second most common cancer all over the world. Ultrasound imaging is an effective tool in the detection of breast cancer because of its non ionizing radiation and low cost. This paper presents the possibility of extraction of features that can effectively differentiate benign and malignant state of cancer using ultrasound images. Speckle noises in the ultrasound images are reduced by mean, median, Weiner, filtering techniques and. Statistical texture features are extracted by applying ridgelet transform. Results shows that the ridgelet based feature extraction can effectively differentiate the state of cancer.Keywords
