The Front Cover shows shell‐by‐shell coated nanoparticle ‘chameleons’—wet‐chemically surface‐modified nanoparticles that can reversibly adjust their dispersibility to entirely orthogonal solvent environments. The reversible and dynamically tunable polarity umpolung of the nanoparticle's surface energies is accomplished through a solvophobic‐interaction‐driven self‐assembly of pristine monolayer‐coated metal oxide nanoparticles with tailor‐designed nonionic amphiphiles. Vividly spoken, this concept of manufacturing nanoparticles with orthogonally adjustable dispersibility in hydrocarbons, fluorocarbons, and water can be compared to a chameleon that changes its color in different environments.
