Instrument designed for the estimation of blood biochemical constituents is nothing but the biochemistry analyzer which is a electronic instrument and used for the investigation of various biochemical constituents like blood glucose, total protein, cholesterol, triglycerides, hemoglobin etc. It is microcontroller based device which is having an inbuilt menu driven programming which make this standalone...
Optoacoustic imaging systems provide a unique opportunity to visualize, with high spatial resolution, the distribution of optical energy in opaque biological tissues and even to visualize the distribution of optically absorbing molecules in tissues. Since hemoglobin of blood is the main tissue chromophore that dominates optical absorption in the near-infrared spectral range, the optoacoustic imaging...
Photoluminescence (PL) from the quantum dots (QD) conjugation suggests a much more sensitive and stable results compared to typical organic fluorescein. Hence, protein labeled by QD can be easily detected using a simple cost effective opto-electrical system. In this study, we immobilize beta-thyroid stimulating hormone (TSH) antibody to the surface of quantum dots (QD) Carcarboxy-EviTag and complete...
A new optical platform for the interrogation of a polymethylmethacrylate (PMMA) multichannel array for chemical and biochemical parameters is described. It consists of a plastic chip formed by two pieces of PMMA properly shaped in order to obtain different microchannels, 500 mum in width and 400 mum in height. A fluorescent sensing layer is immobilized on the internal wall of the microchannel. The...
Light modulation between B and M states of Bacteriorhodopsin films is controlled photo-dynamically for optical Fourier spatial filtering. The technique is applied to display only microcalcifications while filtering out the background in mammograms in real-time.
We report a new label-free biosensor system for protein interaction characterization. The system consists of a VCSEL, a plastic guided mode resonant filter, and a pin detector. The sensor has high sensitivity and ultra compactness, consumes low power, and can be fabricated in 2D arrays.
Computer simulations based on the photon diffusion theory are carried out to analyze the feasibility of measuring the percent carboxyhemoglobin (%HbCO) using the pulse-oximetry technique. A series of in vitro experiments using a mechanical pulser to simulate the pumping effect of the heart is performed. Both the theoretical and the experimental data show that a pulse-oximetry technique using multiple...
