Natural structural color materials, especially those that can undergo reversible changes, are
attracting increasing interest in a wide variety of research fields. Inspired by the natural …

In this brief review we address a range of interesting applications and prospects of
responsive hydrogel thin films for the fabrication of “smart” responsive surfaces, membranes …

Hydrogels are formed when a three‐dimensional polymeric network is loosely crosslinked.
They are swollen by water but not dissolved in it. Hydrogels may display reversible sol–gel …

The synthesis, swelling kinetics, and optical diffraction of inverse opal hydrogel sensors (see
Figure) are demonstrated. Colloidal crystal templating is used to prepare …

1. INTRODUCTION Holographic sensors are analytical devices that systematically diffract
narrow-band light in the ultraviolet to near-infrared range for application in the detection and …

Analyte-sensitive hydrogels that incorporate optical structures have emerged as sensing
platforms for point-of-care diagnostics. The optical properties of the hydrogel sensors can be …

Photonic crystal (PC) based bioassay techniques have many advantages in sensitive
biomolecular screening, label‐free detection, real‐time monitoring of enzyme activity, cell …

A glucose-sensitive inverse opal hydrogel was synthesized through photopolymerization of
2-hydroxyethyl methacrylate and 3-acrylamidophenylboronic acid within the interstitial …

In this tutorial review the use of stimulus-sensitive hydrogels as sensors and actuators for
(micro) analytical applications is discussed. The first part of the article is aimed at making the …

As populations expand worldwide, medical care will need to diversify its data collection
techniques to be able to provide adequate healthcare to global populations, this can be …
