Synthesis and characterization of GHE nanocatalyst. A Schematic representation of the synthesis procedure of GHE nanocatalyst. B TEM image of GNRs. Scale bar: 50 nm. C SEM image of GHE-Tli08105. Scale bar: 200 nm. Evaluation of thermogenesis of aqueous GNRs mediated by 808 nm NIR D with 50 μg/mL at different power densities; E with different concentrations at the density of 2.0 W/cm². UV–Vis absorption spectrum of F arginase Tli08105 and G asparaginase Tli10209 before and after assembly with GNR or GH. The hydrodynamic size of H GNR- and I GH-thermozyme nanoparticles by DLS. J Zeta-potential of GNRs and GH before and after thermozyme-modification. The particle size, polymer dispersity index (PDI) and zeta-potential are presented in the table (bottom)
