Janus droplet as a catalytic micromotor [PDF]
Europhysics Letters, 2015 Self-propulsion of a Janus droplet in a solution of surfactant, which reacts on a half of a drop surface, is studied theoretically. The droplet acts as a catalytic motor creating a concentration gradient, which generates its surface-tension-driven motion;

Motorized DNAzymes Drive Enhanced Electrochemical Biosensing for Rapid Bacterial Detection. [PDF]
Small MethodsThe micromotor DNAzyme analyzer (Motolyzer) enables sensitive electrochemical detection of Legionella pneumophila proteins in unprocessed samples with high specificity. Upon target recognition, DNAzymes actively release redox barcodes, which are detected on DNA‐functionalized electrodes.

Programmable Nanoscale Motion via Molecular Patterning on DNA Origami. [PDF]
Angew Chem Int Ed EnglDNA origami nanorods enable precise urease placement with tunable coverage and asymmetry, revealing that propulsion depends on a balance of catalytic loading and geometry. Maximum speed occurs at ∼25% end‐coverage and declines as enzyme distribution becomes more symmetrical.
