About this collection
Guest edited by Dr Gemma-Louise Davies (University College London) and Professor Marek W Urban (Clemson University).
Stimuli-responsive materials have become popular in materials chemistry in recent years, towards applications in biosensing, on-demand drug delivery, tissue generation, and smart coatings. In particular, such materials have enormous potential for medical diagnostics, for lab-on-a chip or in vivo identification and diagnosis of disease. New materials, based on inorganic complexes, organic ligands, polymers and multifunctional nanostructures, have demonstrated intriguing properties capable of changing or ‘switching’ signal in the presence of an environmental stimulus indicative of disease, providing a unique approach to positive diagnosis.
This Themed Issue in Journal of Materials Chemistry B aims to explore the latest developments in the design, preparation, novel function and application of materials for healthcare diagnostics.
