In this way, a reproducible cooking result as well as an output of the nutritional values and the actual energy content of the prepared food can be made possible.

Systems, apparatuses, and methods are described herein for disease detection using an analyte-agnostic approach. Such systems, apparatuses, and methods can include using an array with hydrogels disposed on a substrate, where the hydrogels include one or more polymerized monomers and one or more photoinitiators or photocleavage products thereof. One or more samples including one or more unlabeled analytes can be contacted with an array of polymers. The samples disposed on the array can be incubated for a first predetermined period of time, and heated at a predetermined temperature for a second predetermined period of time. An imaging device (e.g., flatbed scanner) can be used to measure an amount of one or more colorimetric or luminescence signals produced by the array after the incubating and heating. A neural network trained using the samples can then be used to predict a diagnostic or disease class for the sample.

The invention relates to a device for a light-spectroscopic analysis of a, for example, liquid sample. In particular, light should be guided through a sample and then detected and/or analyzed photometrically, spectrophotometrically, fluorometrically, spectrofluorometrically and/or by means of phosphorescence or luminescence.

A method comprises: aspirating a sample through a needle capillary into a chamber having first and second windows, the capillary and chamber both affixed to a moveable robotic arm; causing a light beam generated by a light source that is affixed to the robotic arm to pass through the sample between the windows; detecting, using a photodetector that is affixed to the robotic arm, a quantity of the light that passes through the sample and the windows; determining an optical absorbance of the sample and a concentration of an analyte in the sample from the detected quantity of light; determining a quantity of the sample to dispense into an analytical apparatus based on the determined concentration; moving the robotic arm so as to cause the needle capillary to mate with an inlet port of an analytical apparatus; and dispensing the determined quantity of the sample into the analytical apparatus.
