Synthesis of Palladium Nanoribbons and Their Application in Electrochemical Detection of Hemoglobin

Autor: Chinnakurli Dwarakanath Shruthi, Gurukar Shivappa Suresh

Publikováno v: Russian Journal of Electrochemistry. 57:380-387

A trustworthy and simple electrode is fabricated using palladium nanoribbons for the determination of hemoglobin. Palladium nanoparticles were synthesised from M. acuminata fruit, which were self assembled to form palladium nanoribbons. Physical char
