Biochem/physiol Actions
Nitrazine Yellow ( 2-(2,4-dinitrophenylazo)-1-hydroxynaphthalene-3,6-disulfonic acid disodium salt) is a pH-sensitive azo dye. It changes color from yellow to blue in pH range 6.0–7.0 and is widely used in microscopy. Throat swab immersed in nitrazine yellow is used to identify pH variations in the vagina before and after amniotomy.

Nanofibres functionalised with pH-sensitive dyes could greatly contribute to the development of stimuli-responsive materials. However, the application of biocompatible polymers is vital to allow for their use in (bio)medical applications. Therefore, this paper focuses on the development and characterisation of
