“…A simple device may consist of an optical fiber coated on the end with a drop of SRG (Fig. 8A) [81,131,132]. Alternatively, the SRG can be coupled to a reflector so that the reflector is moved in response to the change of the hydrogel volume.…”

“…To overcome these disadvantages, optrodes utilizing swellable polymers functionalized to respond to pH have been developed [10][11][12][13][14][15][16]. Polymer swelling has several advantages over detection methods involving chromophores.…”

“…Several studies [13][14][15][16] which have been undertaken on polymer swelling for optrodes have focused on the development of formulations to prepare derivatized polystyrene that can undergo a large number of swelling and shrinking cycles without cracking. The optical properties of the derivatized polystyrene changes with swelling in aqueous solution.…”

“…These probes can be either extrinsic or intrinsic in nature, but the possibility of measurement only at the probe location point, generally at the distal ends, is a drawback. Other techniques such as laser-induced fluorescence systems [12,13], optically sensitive membranes coupled to an optical reflective device [14], surface-enhanced Raman spectroscopy, spark excitation fiber optic spectrochemical emission sensors, and chemical optrode-based sensors [15] have been used for several types of liquid chemical sensing. However, these extrinsic sensors generally cause high insertion loss and exhibit ingress/egress connection problems (into and out of the light modulator).…”
