A chitosan grafted mesoporous carbon aerogel for ultra-sensitive voltammetric determination of isoniazid.

A screen-printed carbon electrode (SPCE) was modified with chitosan (Chit) supported on carbon aerogel (CA) to obtain an electrochemical sensor for the tuberculosis drug isoniazid (INZ). The interconnected mesoporous structure of Chit/CA provides a large surface area (S = 461 m g) and good porosity (V = 0.69 cm g).
