In this study, lignin has been used as stabilizing agent during electrochemical synthesis of copper based nanocolorants. Brown, green and blue colored colloidal suspensions of nano particles have been produced under different electrolysis process conditions using copper electrodes.
These lignin derived nanocolorants support cell division without any physical damage and minimize photo quenching. The nontoxicity of these colorants and their fluorescent ability coupled with mammalian live cell staining ability make them an excellent candidate for cell imaging.
I hope you find this article thought-provoking.Dr. Mamatha M Pillai, PhD
