Sensors
Graphene's exceptional electrical conductivity, sensitivity and high surface area make it ideal for developing highly responsive and accurate sensors across various applications
We specialize in the production of reduced graphene oxide (rGO) ideal for the development of high-performance sensors. rGO’s excellent conductivity enhances signal detection in sensors by amplifying small environmental changes, making it a versatile and cost-effective alternative to pristine graphene. rGO also has the benefit of being more suited for functionalization, enabling the grafting of one or more receptor molecules onto the graphene material.
Why graphene is ideal for advanced sensor applications
Graphene is revolutionizing sensor technology with its unique properties that enable higher sensitivity, faster response times, and greater efficiency across a range of fields. Here are some of the extraordinary properties of graphene that makes it perfect for the field of sensors
High conductivity
Graphene’s superior conductivity allows for precise detection of even the smallest changes in environmental conditions, making it ideal for electrical sensors that rely on signal amplification.
High surface area
With and incredibly high surface area-to-mass ratio, graphene maximizes interaction with target molecules, significantly improving sensitivity in sensors, particularly in gas and chemical detection. This also translates to a large available area for functionalization.
Biocompatibility
Graphene’s biocompatibility allows for its use in biosensors that can detect biomolecules or monitor health conditions, expanding its application into medical diagnostics and healthcare tech.
Lightweight and thin
Graphene is extremely lightweight and thin, allowing sensors to be compact and integrated into space-limited environments without sacrificing performance or sensitivity.
Mechanical flexibility
Graphene’s flexibility enables the creation of sensors that can be integrated into wearable or flexible electronics, maintaining high performance in bendable devices.
Chemical stability
Graphene’s strong resistance to harsh chemical environments ensures long-lasting performance, making it ideal for sensors in industrial or environmental monitoring where durability is essential.
Applications
Biosensors
Graphene-based biosensors are highly effective in selectively detecting specific chemical markers in biological systems, such as for early disease detection. This is all due to graphene’s excellent charge mobility, large surface area and biocompatibility, making it ideal as a safe and efficient substrate for receptor molecules.
Photoelectric sensors
Graphene-based photoelectric sensors are highly efficient due to graphene’s high electrical conductivity and transparency. The sensors convert absorbed photons into electrical current, with a wider wavelength range and faster response time than conventional photodetectors.
Chemical sensors
Graphene is an outstanding material for developing better field-effect transistors (FETs) due its high chemical stability, ultra-high mobility, and low resistivity. These properties make it an excellent candidate for creating more efficient chemical sensors.
Magnetic field sensors
Graphene's magnetoresistance and high carrier mobility enable it to detect magnetic fields with high sensitivity and precision. Its linear response, along with a wide operating range in temperature and field strength, makes it ideal as magnetic sensors.
Gas sensors
Graphene-based gas sensors detect gas molecules by measuring changes in electrical conductivity when gas is adsorbed on graphene’s surface. The sensors are extremely sensitive due to graphene’s low noise and allows the detection of even a single gas molecule.
Mechanical sensors
Graphene-based mechanical sensors are ideal for detecting physical changes like strain, pressure and force due to graphene’s excellent conductivity and mechanical properties. These sensors operate through resistive, capacitive, and piezoelectric methods, offering ultrahigh sensitivity, fast response times and a wide detection range.
