摘要： A microfluidic device useable for performing live cell computed tomography imaging is fabricated with a cover portion including a first wafer with at least one metal patterned thereon, a base portion including a second wafer with at least one metal patterned thereon and negative photoresist defining recesses therein, and a diffusive bonding layer including a negative photoresist arranged to join the cover portion and the base portion. A composition useful in live cell computer topography includes a long-chain polysaccharide at a concentration of from about 0.01% to about 10.0% in cell culture medium for supporting cell life while enabling cell rotation rate to be slowed to a speed commensurate with low light level imaging.

摘要： Novel methods and devices including modified endoscopes that employ fiber optic technology and multiple extrinsic optical sensors for enablement of simultaneous determination of change rates of biological analytes in vivo with single-cell resolution. The devices employ dynamic oscillatory actuation to determine the gradient of analytes of interest along one or multiple directions with respect to the cell. The change rate or flux of the analyte of interest can be easily determined by applying the first Fick's law that relates the flux with the concentration gradient. The dual operation mode of the device markedly increases measurement sensitivity and accuracy.

摘要： An integrated technological platform enabling real-time quantitative multiparameter metabolic profiling, utilizing either or both of extra and intracellular optical sensors, individually or simultaneously. A scalable embedded micropocket array structure, generally fabricated on fused silica substrates, facilitates the integration of multiple, spatially separated extracellular sensors for multiparameter analysis in a container formed with the use of an activation mechanism forming part of a device configured to hold the container during the measurements. The creation of hermetically sealed microchambers is carried out with a pneumatically and/or mechanically and/or electromechanically driven device that is “floating” within the holding device and that is optionally equipped with a vacuum/suction mechanism to hold a component of the container at its surface.

摘要： A triple sensor structured for simultaneous measurement of glucose, oxygen, and pH. The sensor components are in thin film states such as sensing films or membranes, with a glucose probe associated with emission of radiation in the blue part of the spectrum, an oxygen probe associated with radiation in red portion of the spectrum, and a pH probe—with a green portion of the spectrum. The optical probes are chemically grafted or immobilized in a suitable polymer matrix, alleviating the leaching of the probes from the matrix, improving the thin film sensing stability, and enabling the repeatable use of the same sensing films.

摘要： A chamber device for analyzing living cell(s). The chamber device includes a base and a lid that when reversibly pressed closed create a chamber. The base is configured with an optically transparent well to contain at least one cell. The lid has a breadth greater than the base and is configured to contain at least one sensor. The lid is further configured with a lip that when pressed between the lid and the base creates an impermeable seal. The base and the lid are configured so that, when closed and in use, the sensor remains spatially apart from the at least one cell.
