Abstract
AbstractNucleic acid‐functionalized liposomes modified at their boundaries with o‐nitrobenzyl phosphate‐caged hairpin units and pH‐responsive C‐G·C+ triplex forming strands are used for the concomitant light and pH‐triggered fusion of three types of loaded liposomes. The fusion processes are followed by light‐scattering size enlargement measurements, optical methods, and biocatalytic cascades activated upon the mixing of the liposomes loaded with enzymes and their substrates and their fusion into the cell‐like containments. The fused liposomes act as functional protocells for the integration of biocatalytic machineries. This is exemplified by the operation of an autonomous polymerization/nickase machinery synthesizing a Mg2+‐ion‐dependent DNAzyme and of a transcription machinery yielding the Malachite Green‐RNA aptamer product.
