Abstract: A micro-plate reader for use with a portable electronic device having a camera includes an opto-mechanical attachment configured to attach/detach to the portable electronic device and includes an array of illumination sources. A slot in the opto-mechanical attachment is dimensioned to receive an optically transparent plate containing an array of wells. Optical fibers are located in the opto-mechanical attachment and transmit light from each well to a reduced size header having, wherein the fiber array in the header has a cross-sectional area that is ≤10× the cross-sectional area of the wells in the plate. A lens located in the opto-mechanical attachment transmits light from the header fibers to the camera. Software executed on the portable electronic device or other computer is used to process the images to generate qualitative clinical determinations and/or quantitative index values for the separate wells.

Abstract: Embodiments described are generally directed to a test sample apparatus. The test sample apparatus generally comprises a holder base arranged that accommodates a tablet or cell phone. The apparatus has a hood that is placed over a portion of the tablets illuminating touchscreen such that the illuminating touchscreen provides light that can be collected by the hood. There is a chamber integrated with the hood adapted to accommodate a chemically activated test strip. The chemically activated test strip is illuminated when the hood collects light from the illuminating touchscreen. A lens in the hood interposed between the camera and the test strip enables the camera to focus on a portion of the chemically activated test strip when the hood is placed over the portion of the illuminating touchscreen.

Abstract: A method for detecting albumin based on a colorimetric assay and a system thereof are disclosed. Gold nanoparticles are added into the sample preparing device having a sample without spectroscopic tags, wherein the sample without spectroscopic tags is formed as the alkaline solution to avoid the interference substances adhering on the gold nanoparticles. The gold nanoparticles are concentrated by using the microfluidic concentrator with the circular ion exchange membrane by applying an external electric field across two electrodes. The image of the concentrated gold nanoparticles is captured by the image capturing device for measuring the saturation intensities of the image, wherein there is a relation between the saturation intensities and the concentration of the albumin in the sample without spectroscopic tags. The concentration of the albumin of the sample without spectroscopic tags is obtained by the relation and the measured saturation intensities.

Abstract: A mobile, self contained molecular diagnostics system is provided with a microfluidic chip, detection apparatus and an integrated or wireless control interface and imager. The system provides automated sample preparation and rapid optical detection of multianalyte nucleic acids and proteins. On chip PCR may be performed to improve the optical fluorescence signal for nucleic acid detections. Plasmonic protein detection is performed using a dark field smartphone microscope. Dark field illumination is based on an evanescent field generated by LED total internal reflection. The smartphone element may also be used as an interface to control the detection apparatus, acquire images, process data and for wireless communications with remote computers. The handheld automated system has low power requirements and is particularly suited for point of care and on demand diagnostics in resource limited settings.
