Too hot to handle: The surroundings of magnetic nanoparticles can be heated by applying a magnetic field. Polymer-coated magnetic nanoparticles were functionalized with single-stranded DNA molecules and further hybridized with DNA modified with different fluorophores. By correlating the denaturation profiles of the DNA with the local temperature, temperature gradients for the vicinity of the excited nanoparticles were determined., (Copyright © 2013 WILEY-VCH Verlag GmbH & Co.

Too hot to handle: The surroundings of magnetic nanoparticles can be heated by applying a magnetic field. Polymer‐coated magnetic nanoparticles were functionalized with single‐stranded DNA molecules and further hybridized with DNA modified with different fluorophores. By correlating the denaturation profiles of the DNA with the local temperature, temperature gradients for the vicinity of the excited nanoparticles were determined. [ABSTRACT FROM AUTHOR]

The determination of temperature increments around excited magnetic nanoparticles is an experimental challenge, and previous reports tend to employ simple and limited methods. In their Communication on page 11526 ff., V. Grazú, J. M. de la Fuente, and co‐workers demonstrate an accurate spatial mapping of the temperature by exposing magnetic nanoparticles that are functionalized with fluorophore‐modified DNA of different lengths to radiofrequency radiation.

Die Bestimmung von Temperaturinkrementen in der Umgebung angeregter magnetischer Nanopartikel ist eine Herausforderung, und bisherige Methoden waren limitiert. In der Zuschrift auf S. 11740 ff. erstellen V. Grazú, J. M. de la Fuente et al. eine akkurate räumliche Temperaturkarte, indem sie magnetische Nanopartikel, die fluorophormodifizierte DNA ‐ Abschnitte verschiedener Länge tragen, mit Radiofrequenzen bestrahlen.
