Abstract

The polymer‐mediated self‐assembly of silica and gold nanoparticles (see inset in Figure and cover) leads to extended aggregates. After calcination and subsequent surface modification, these aggregates serve as supports for the covalent immobilization of lipase (see Scheme). The obtained biocatalysts exhibit high efficiencies and long‐term stability.

30. Calcinations were carried out using a slow temperature ramp 20–500°C over 9 h with a ceiling temperature of 500 °C for 3 h.
31. A carbonyl band could not be determined conclusively due to the very low concentration of carboxylic acids within the organic monolayer.
32. At 200 keV the wavelength of the electron beam is calculated to be 2.73 pm; see T. B. Rymer Electron Diffraction Butler and Tanner London1970.

34. It should be noted that the biocatalysts are recyclable; the extent however has not been quantified.
