Optical sensing material for pH detection based on the use of roselle extract

This research assessed the potential of natural colour extract of Hibiscus sabdariffa L. (roselle) as sensing material. The pH sensor was developed based on the use of natural reddish colour in roselle calyx, delphinidin-3-sambubioside immobilised in a glass fibre filter paper. In free solution, ros...
