Janus-Nanojet as an efficient asymmetric photothermal source

The combination of materials with radically diferent physical properties in the same nanostructure gives rise to the so-called Janus efects, allowing phenomena of a contrasting nature to occur in the same architecture. Interesting advantages can be taken from a thermal Janus efect for photoinduced h...

description The combination of materials with radically diferent physical properties in the same nanostructure gives rise to the so-called Janus efects, allowing phenomena of a contrasting nature to occur in the same architecture. Interesting advantages can be taken from a thermal Janus efect for photoinduced hyperthermia cancer therapies. Such therapies have limitations associated to the heating control in terms of temperature stability and energy management. Single-material plasmonic nanoheaters have been widely used for cancer therapies, however, they are highly homogeneous sources that heat the surrounding biological medium isotropically, thus equally afecting cancerous and healthy cells.
