Surface Functionalisation

Surface functionalisation is a critical aspect of many applications in optics, photonics, sensors, biomedical devices, and more.

Surface functionalisation takes a material whose surface chemistry is dictated by that material's surface composition and surface properties, and attaches to it specific chemical functional groups, or biochemical functionalities, to impart tailored physical, chemical, or biochemical properties to that material's surface.Ìý

Acetyl-coenzyme A (Acetyl-coA) biochemical, molecular model

By manipulating a material's optical properties or introducing specific functional groups that interact in controlled ways with molecules in fluids, we can enhance its capabilities. This includes incorporating receptors for chemical or biochemical specificity on sensor surfaces.

The powerful combination of capabilities available at Optofab Adelaide and at the , coupled with Optofab's competence for synthetic and surface chemistry in the functionalisation of glass fibres,Ìýallows us to provide cutting-edge surface functionalisation, paving the way for novel optical-based fibre sensors.

This collaborative effort underscores Optofab's commitment to advancing fibre-based platform technologies with applications in human health, environmental monitoring, industrial processes, and defence systems.
