- •
The sensor shows impressive electro-catalytic activity towards Tyrosine.
- •
The symbiotic effect of modification enhances the current of Tyrosine by 5.5 times compared to CPE.
- •
Successful quantitative estimation of Tyrosine in food and biological samples.
- •
Tyr undergoes 1 e− and 1H+ transfer process at the modified electrode.
- •
Sensitive and selective towards Tyrosine in the presence of various interferents.
