Poly(2‐alkyl‐2‐oxazoline) (PAOx) coated gold nanoparticles (PAOx@AuNPs) are synthesized in a straightforward manner leading to molecular AND logic gates that respond to environmental changes in ionic strength and temperature. As reported by R. Hoogenboom and colleagues on page 2511, the variation of the PAOx composition grants control over the temperature input value. This direct functionalization strategy can be extended to the development of PAOx@AuNPs, of high interest in biotechnology.
