From: Fabrication of fluorescent pH-responsive protein–textile composites
Wearable protein–textile composites for fluorescent pH sensing. (a) A scheme representing the steps involved in the working of our textile–protein sensor. (b) Fluorescence intensities of the textile at pH conditions ranging from 3–11 in three types of solutions—artificial sweat, Carmody buffers and phosphate-citrate buffers. The non-linear fit for all three curves was performed using the Henderson–Hasselbalch equation (Eq. 4). (c) The reversible fluorescence behavior of the acrylic–CsgA–pHuji composite observed at two distinct pHs (pH 3 and pH 10) over 10 cycles.
