摘要:
The invention relates to a carrier for a thin layer and a method for the analysis of molecular interactions on and/or in such a thin layer. A thin layer disposed on a carrier is illuminated with electromagnetic radiation from at least one radiation source and a reflected radiation part on boundary surfaces of the thin layer is detected by means of an optoelectronic converter that converts the detected radiation into a frequency- and intensity-dependant photocurrent. A reading voltage is applied to the optoelectronic converter. By changing the reading voltage, the spectral sensitivity of the optoelectronic converter is varied such that a substantially constant photocurrent is obtained. Alternatively or in addition to varying the spectral sensitivity by changing the reading voltage, the reflected radiation part is detected with an optoelectronic converter that is designed as a sensor layer in the carrier. The carrier is particularly characterized in that it comprises a substrate on which at least one sensor layer with optoelectronic properties is disposed.

摘要:
The present invention relates to a retina implant for the functional electrostimulation of a retina as a function of incident light. The retina implant has a stimulation chip that is designed to be implanted in the area of the retina of an eye. It further includes a radiation receiver that provides energy for the stimulation chip as a function of invisible radiation that occurs. In accordance with one aspect of the present invention, the radiation receiver is designed so as to be implanted in the area of the eye in a fashion spatially separated from the stimulation chip. The stimulation chip also has decoupling means in order to separate invisible scattered radiation from impinging visible light.
