摘要:
Microplate assemblies and methods for using same are provided. In accordance with some embodiments, microplate assemblies are provided, the assemblies comprising a microplate well portion that forms a microplate well and that includes at least one sensor in the microplate well that responds to analyte in the well. In accordance with some embodiments, methods for determining a cell consumption rate of an analyte are provided, the methods comprising: positioning a cell in a microplate well having at least one sensor located within the well; providing analyte to the microplate well at a controlled rate; detecting a response of the sensor to the analyte in the microplate well; and determining a cell consumption rate of the analyte based on the response of the sensor to the analyte.

This disclosure relates generally to potassium ion sensors and monomers derived from such sensors. The disclosure also provides for polymers (e.g., random copolymers, nanoparticles, polymer thin films, and sensors) having polymerized monomeric potassium ion sensors as described herein. These compounds and polymers are useful for measuring intracellular and extracellular potassium ion concentrations.
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.
