What Types of Nanomaterials are Used in pH Sensors?
Various nanomaterials are employed in the development of pH sensors:
Carbon Nanotubes (CNTs): Known for their excellent electrical properties and high surface area, CNTs are commonly used in pH sensors to enhance sensitivity and response time. Gold Nanoparticles (AuNPs): These nanoparticles are highly conductive and can be functionalized with different chemical groups, making them suitable for selective pH sensing. Graphene: With its exceptional electrical conductivity and large surface area, graphene is increasingly used in pH sensors for its high sensitivity and rapid response. Silicon Nanowires: These nanowires offer high sensitivity and can be easily integrated into electronic devices, making them ideal for pH sensing applications.
