I am going to carry out research in this area. I would like to apply these materials as biocatalysts for biodiesel production. I am trying to get challenges in this field so if you have related materials and ideas, please provide me some details.
There is a paper not exactly with enzymes but with sugars from honey as capping agents for gold and silver nano particles and pd and fe nanoparticles. Honey Mediated Green Synthesis of Pd Nanoparticles for Suzuki Coupling and Hydrogenation of Conjugated Olefins, Nanosci. Nanotechnol. Lett. 2012, 4, 420-425. S. M. Reddy, K. K. R. Datta, Ch.
