Hard‐shell case : Using a (RKK) 4 D 8 peptide allows mineralization to occur under cytocompatible conditions. Thus individual Chlorella cells could be encapsulated within a SiO 2 –TiO 2 nanoshell with high cell viability (87 %). The encapsulated Chlorella showed an almost threefold increase in their thermo‐tolerance after 2 h at 45 °C.
