Advancing biomedical diagnostics: Graphene sensor inks pave the way for precision biosensing

Haydale has created a range of functionalised biomedical sensor inks for use in biosensing and diagnostic applications. These inks include functional groups that allow them to interact with biological compounds like proteins and DNA, enabling the identification of particular analytes.

Functionalised graphene sensors

Haydale began working with Cardiff University in 2021, specifically the Wales Kidney Research Unit (WKRU), to create a prototype biosensor using its functionalised biomedical sensor inks.

The biosensor was developed to detect particular electrochemical urinary microRNAs, eliminating the requirement for invasive biopsies to diagnose delayed graft function in kidney transplant patients.

Graphene sensors for faster and more accurate results

The new detection technique is faster and less expensive compared to the currently used PCR tests. The use of graphene as a sensory ink improves electrical conductivity, sensitivity, and reaction rate in a biomedical sensor, allowing for faster and more accurate findings than existing approaches.

Haydale has expanded its product portfolio to include a range of functionalised biomedical sensor inks for a variety of applications, such as glucose monitoring, gout detection, and kidney disease diagnosis.

These inks have the ability to revolutionize the field of biosensing and diagnostics, resulting in the creation of novel, more precise diagnostic tools and therapeutics for a wide range of diseases.

About Haydale Limited

Haydale is a global technologies and advanced materials group that facilitates the integration of graphene and other nano-materials into the next generation of commercial technologies and industrial materials.

Headquartered in Wales, UK but with operational sites across the globe, Haydale Graphene Inc. was established in 2003. Now with over 70 people and partners include Petronas, Saint-Gobain & Vittoria Tyres as well as many regional partners in fields ranging from Thermal Fluids, Bio-sensors, Concrete Coatings, Composites, Hydrogen Cells, Automotive Heating and Underfloor Heating.

Haydale Graphene Inc. comprises two complementary advanced material businesses, both leaders in their respective fields:

  • Plasma functionalisation of nano-materials for third party applications and manufacture of plasma-functionalised graphene-enhanced products, all primarily based in the UK.
  • Manufacture and sale of Silicon Carbide cutting tools and powders based in the US.

Haydale has a unique, patented HDPlas™ functionalisation process that treats nano-material powders by using plasma and bleeding in the required chemistry as a gas to achieve the necessary result. This is a highly tuneable, environmentally clean means of functionalisation suitable for any application and grade of nano-material that does not require the use of acids or surfactants used by other functionalisation processes. Haydale does not manufacture graphene or boron nitride, but has characterized over 250 types of 3rd party graphene in order to understand which ones are appropriate for different applications.

Our advanced HDPlas™ functionalisation process has consistently proven its capability to modify surface properties of traditionally difficult-to-treat powders.

The HDPlas™ system offers flexibility in surface chemistries, allowing for custom solutions based on the intended application. This is especially attractive in the field of thermal management, where many different polymer systems are used.
