Catalan research centre develops a low-cost device that turns a smartphone camera into a portable lab.
Use the biosensor and camera combo to quantify the presence of analytes in a sample with or without the need for specific receptors. The proof of concept uses paper embedded with graphene quantum dots, but other formats are feasible.
Currently seeking partners for technical cooperation and/or license agreement.
The proposed technology is a detection device that uses a smartphone camera to quantify analytes in a given sample. The proof of concept can detect the presence of phenols and polyphenols in water, food and wine samples using paper strips embedded with graphene quantum dots as the sensor.
It paves the way for fast and simple screening of organic compounds in the field, and the detection of various compounds in combination with specific receptors.……
The use of eco-friendly graphene quantum dots avoids the use of heavy metal-based ones
The technology doesn’t need sophisticated instrumentation, making this versatile technology ideal for remote settings.
How it works: the device uses an ultraviolet LED to excite the graphene quantum dots embedded in the paper-based sensor after exposure to the sample. The smartphone camera is used to take a picture of the excited dots, upon which software analyses their luminescence and gives a reading. If the intensity of the light emitted by the quantum dots is softened, this is indicative of the presence of analytes and can be measured to establish the precise concentration
