Optoelectronic chip

Optoelectronic chip according to any one of the preceding claims, characterized in that the thin-film heating element is equipped with a temperature sensor, preferably in the form of a thin-film temperature sensor, and preferably a control unit is also provided to control and/or regulate the thin-film heating element based on the measurement data acquired by means of the temperature sensor.

Optoelectronic chip according to any one of the preceding claims, characterized in that the heating element is optically transparent and/or consists of an indium-tin-oxide compound.

Optoelectronic chip according to any one of the preceding claims, characterized in that the thin-film heating element is or comprises a resistance heating element.

Optoelectronic chip according to any one of the preceding claims, characterized in that a sensor layer is further provided, which preferably has metal and/or consists of metal and which preferably at least partially covers an outer surface of the optoelectronic chip and is further preferably designed to come into thermal contact with a sample.

Optoelectronic chip according to any one of the preceding claims, characterized in that an outer surface of the optoelectronic chip, which is designed to come into contact with a sample, at least partially or completely has a surface modification and/or surface functionalization in order to bind molecules contained in the sample, in particular biological molecules.

Use of an optoelectronic chip according to any one of the preceding claims for receiving a sample in the visualization of temperature-sensitive processes, wherein a sample, preferably an at least partially liquid, solid or gel-like sample is applied to the optoelectronic chip in such a way that the sample partially or completely surrounds the thin-film lightguide.

Optical system, preferably a microscope, which is designed to be used with an optoelectronic chip according to any one of the preceding claims, having at least one emitter or scatterer that emits light for optical excitation of the sample parallel to the plane of the thin-film lightguide and having at least one detector that detects light deflected by the sample normal to the plane of the thin-film lightguide.
