    摘要: A noninvasive remote parameter sensor and sensing method is provided that is particularly suited for the remote monitoring of skin temperature. The sensor and sensing method utilize luminescence-based sensors that are non-toxic and non-irritating to the skin. The sensor preferably utilizes one or more types of fluorophores that are embedded in a soft hydrogel. The sensor is illuminated with excitation light, and temperature is monitored by detecting and analyzing the emission light from the fluorophores. Because a soft hydrogel is used, the sensor can be gently wiped off the skin at the conclusion of temperature measurements.

    摘要: A protein sensing molecule is capable of binding an analyte in a sample. The protein sensing molecule includes a first detectable quality that changes in a concentration dependent manner when the protein sensing molecule is bound to the analyte. The protein sensing molecule also includes a second detectable quality that does not undergo substantial change when the protein sensing molecule is bound to the analyte. The protein sensing molecule may be used in methods for characterizing samples and may also be used in sensors.

    摘要: The present invention provides ratiometric fluorescent pH sensors for non-invasive, continuous monitoring of pH in such applications as fermentation processes. The ratiometric fluorescent pH sensors comprise a fluorescent dye that exhibits a shift in excitation wavelength with a corresponding shift in pH in the local environment of said fluorescent dye. Ratiometric measurements of the emission intensities at dual excitation maxima correlate to pH. Also provided is a fluorescent dye 6-methacryloyl-8-hydroxy-1,3-pyrene disulfonic acid (MA-HPDS). Further provided are systems and methods to non-invasively and continuously monitor pH.
