When in use, the cartridge is engaged with the reader component and a fluid sample is placed into the first well. The reader component controllably illuminates the third well and comprises a detector that detects differences in photocurrent and/or spectra between the reference signal and the sample signal from the illuminated third well.

The present disclosure relates to an apparatus or methodology for detecting one or more contaminants and/or measuring watering quality in a water supply system, which may be installed at any place chosen by a user so as to detect the one or more contaminants and/or measure the quality of water flowing through a pipe of the water supply system, such as tap water, water purifier, drinking water storage facility, or water intake facility. The present disclosure provides numerous benefits over the existing technology including convenience of handling with ease and safe fastening and installment of the apparatus for detecting one or more contaminants and/or measuring quality of water. Furthermore, the present technology enables the monitoring of the contamination level of the water delivered in the water supply system at any time chosen by the user because the contamination can be detected and/or the water quality can be measured and monitored in a wireless environment either continuously or intermittently through a wireless communication system with a remote user device.

This invention relates to a semi-quantitative diagnostic tool and a method for using the same to verify the efficacy of cleaning-in-place procedures in eliminating carbohydrate-based, organic residues from product contact surfaces in food, beverage and pharmaceutical manufacturing, processing and packaging facilities. The diagnostic tool comprises a permanganate-based colorimetric indicator formulation and a translucent assay container for containing the permanganate-based colorimetric indicator formulation. The diagnostic tool is characterized therein that the permanganate-based colorimetric indicator formulation is admixed with a product sample to be tested so that the admixed permanganate-based colorimetric indicator formulation undergoes a colorimetric reaction in the presence of organic residues in the product sample, the arrangement being such intensity of the colorimetric reaction displayed provides a semi-quantitative determination of a concentration of organic residue dissolved or suspended in the product sample.

The present invention generally relates to systems and methods for receiving blood (or other bodily fluids) from a subject, e.g., from or beneath the skin of a subject. In some cases, the blood (or other bodily fluids) may be deposited on a membrane or other substrate. For example, blood may be absorbed in a substrate, and dried in some cases to produce a dried blood spot. In one aspect, the present invention is generally directed to devices and methods for receiving blood from a subject, e.g., from the skin, using devices including a substance transfer component (which may contain, for example, one or more microneedles), and directing the blood on a substrate, e.g., for absorbing blood. The substrate, in some embodiments, may comprise filter paper or cotton-based paper. After absorption of some blood onto the substrate, the substrate may be removed from the device and shipped or analyzed. In some cases, the device itself may be shipped or analyzed. For example, in some embodiments, a portion of the device may be sealed such that the substrate is contained within an airtight portion of the device, optionally containing desiccant. Other aspects are generally directed at other devices for receiving blood (or other bodily fluids), kits involving such devices, methods of making such devices, methods of using such devices, and the like.

A method of determining pathogen inactivation may include performing an energy balance on a fluid heating system. Performing an energy balance may include calculating temperatures of a fluid at a plurality of locations as the fluid flows through the fluid heating system. The method of determining pathogen inactivation may also include receiving inactivation kinetic data regarding a pathogen present in the fluid and determining pathogen inactivation amounts based on exposure to the temperatures. Performing an energy balance may include receiving a plurality of input parameters relating to the fluid heating system.

Provided herein are methods for selectively detecting an alkyne-presenting molecule in a sample and related detection reagents, compositions, methods and systems. The methods include contacting a detection reagent with the sample for a time and under a condition to allow binding of the detection reagent to the one or more alkyne-presenting molecules possibly present in the matrix to the detection reagent. The detection reagent includes an organic label moiety presenting an azide group. The binding of the azide group to the alkyne-presenting molecules results in emission of a signal from the organic label moiety.
