Abstract
The underlying objective is to create an optoelectronic sensor system which illuminates the specimen homogenously and only allows produced fluorescent light to reach the photoactive layer. The objective is achieved substantially by creating a total reflection layer for the introduced light before or above the optoelectronic sensor layer. This can be applied in all fields in which microarray biochips are used.
Claims15
An optoelectronic sensor system for stimulating and detecting specimens, with a surface for the application of the specimens and an underlying layer system with a transparent first layer with a first refractive index, into which light can be introduced for stimulating the specimen, and an adjoining second layer with a second smaller refractive index for generating a total reflection of the introduced light and a resulting spreading planar lightwave in the first layer and an optoelectronic sensor layer lying under the second layer comprising one or more semiconductor layers between two electrode layers, of which the electrode layer facing the specimen is designed to be at least partly light permeable, further comprising two glass layers wherein the optoelectronic sensor layer is located between two glass layers.
An optoelectronic sensor system, comprising:
- a first glass substrate for applying microarray spots on its surface,
- a second glass substrate as a substrate for the sensor,
- a third glass substrate as encapsulation for the sensor,
- a photosensitive optoelectronic layer lying between the second and the third glass substrates including one or more semiconductor layers between two electrode layers, of which the electrode layer facing the specimen is designed to be at least partly light-permeable,
- a PDMS intermediate layer between the first and the third glass substrate, and
- a prism arranged on the surface of the first glass substrate, which introduces the lightbeam emitted from a light source at a specified angle into the first glass substrate, where it is guided under total reflection to the PDMS intermediate layer.
An optoelectronic sensor system comprising a light source for stimulating specimens, with a surface for the application of the specimens and an underlying layer system with a transparent first layer with a first refractive index, into which light can be introduced for stimulating the specimen, and an adjoining second layer with a second smaller refractive index for generating a total reflection of the introduced light and a resulting spreading planar lightwave in the first layer and an optoelectronic sensor layer lying under the second layer comprising one or more semiconductor layers between two electrode layers, of which the electrode layer facing the specimen is designed to be at least partly light permeable,
- wherein the stimulating light source comprises a laser, LED or OLED for producing light having a wavelength of 300-650 nm, and
- wherein the photosensitive layer is formed from an organic semiconductor.
