Hydrogels are excellent water-swollen polymeric materials for use in wearable, implantable,
and disposable biosensors. Hydrogels have unique properties such as low cost, ease of …

Conceptual and commercial examples of implantable sensors have been limited to a
relatively small number of target analytes, with a strong focus on glucose monitoring …

A sensing hydrogel was demonstrated using pH-sensitive surface-enhanced Raman
scattering (SERS) reporters embedded in modular microdomains. The gold nanoparticle …

Now that a fully-implantable, continuous glucose monitor has received FDA approval, optical
techniques other than fluorescence will seek to overcome the limited lifetimes resulting from …

Many diagnostic tests for disease management and overall health monitoring provide only
an instantaneous measurement of the patient's state of health, leaving intermediate …

Reversible SERS-active sensing assays made from plasmonic nanoparticles encapsulated
in biocompatible matrices have potential as long-term implantable sensors. These assays …
