A photoresponsive ionogel comprising a photo-responsive polymer polymerised within an ionic liquid matrix is described. This solid-state electrolyte material maintains its ionic liquid characteristics but these characteristics can be altered upon irradiation of the gel with light of a particular wavelength. By suitably configuring the ionogel through the incorporation of specific ions within the gel it is possible to cause dramatic changes in properties of the ionogel such as viscosity, conductivity, acidity, basicity and polarity using light as the stimulus.
A flow analysis apparatus is disclosed. The flow analysis apparatus has at least one wicking channel fluidically coupled to an absorbent pump. A wicking valve is fluidically coupled to the wicking channel to provide a fluidic connection to the sample source where opening the wicking valve allows the absorbent pump to cause liquid to flow down the wicking channel toward the absorbent pump. Other similar wicking valves can be added to provide functions such as calibration and reagent addition. A detection unit allows for analysis of the liquid as it flows down the wicking channel.
A self-maintained chemical sensing system is disclosed. According to the devices and methods of the invention, it is shown that the BCG-based colorimetric sensor could be reproducibly moved between the predefined site to accomplish the self-maintaining and colorimetric measurement. Colorimetric measurements are achieved by analyzing RGB changes using a video camera or by monitoring photocurrent using an LED emitter and LED detector. The calculated energy consumption rate was ~ 0.17 J / cm<2>per cycle for a self-maintained and/or autonomous low cost chemical sensor.
A chemochromic sensor includes multiple bi-directional LEDs, each optically aligned with one or more test areas. Each LED is used as both a light emitter when driven in forward bias, and as a light detector when driven in reverse bias. By alternating the bias on the LEDs, multi-way light measurements of the test area can be obtained.
