Correction: Corrigendum: Effect of magnetic dipolar interactions on nanoparticle heating efficiency: Implications for cancer hyperthermia
Luis C. Branquinho,Marcus S. Carrião,Anderson S. Costa,Nicholas Zufelato,Marcelo Henrique Sousa,Ronei Miotto,Robert Ivkov,Andris F. Bakuzis +7 more
TL;DR: In this paper, the influence of particle chain formation on the normalized heating properties, or specific loss power (SLP) of both low-spherical and high-parallelepiped anisotropy ferrite-based magnetic fluids was explored.

Effect of magnetic dipolar interactions on nanoparticle heating efficiency: Implications for cancer hyperthermia
Luis C. Branquinho,Marcus S. Carrião,Anderson S. Costa,Nicholas Zufelato,Marcelo Henrique Sousa,Ronei Miotto,Robert Ivkov,Andris F. Bakuzis +7 more
TL;DR: Analysis of ferromagnetic resonance data shows that high particle concentrations correlate with increasing chain length producing decreasing SLP, and a theoretical model describing dipole interactions valid for the linear response regime is proposed, predicting optimum particle sizes for hyperthermia to about 30% smaller than those previously predicted, depending on the nanoparticle parameters and chain size.
Journal ArticleDOI
Real-time infrared thermography detection of magnetic nanoparticle hyperthermia in a murine model under a non-uniform field configuration.
Harley F Rodrigues,Francyelli Mariana dos Santos Mello,Luis C. Branquinho,Nicholas Zufelato,Elisângela de Paula Silveira-Lacerda,Andris F. Bakuzis +5 more
TL;DR: The results indicate that infrared thermography may be a promising tool for both early cancer detection and forhyperthermia treatment (at least for subcutaneous tumours), since the method permits access to information about the intratumoral temperature during a real-time magnetic hyperthermia as well as to estimate the in vivo nanoparticles SLP.
Journal ArticleDOI
Precise determination of the heat delivery during in vivo magnetic nanoparticle hyperthermia with infrared thermography
Harley F Rodrigues,Gustavo Capistrano,Francyelli Mariana dos Santos Mello,Nicholas Zufelato,Elisângela de Paula Silveira-Lacerda,Andris F. Bakuzis +5 more
TL;DR: The results indicate that temperature errors as large as [Formula: see text]C can occur if the experiment is not properly designed, and how to precisely monitor temperature with IRT during hyperthermia is shown, which could positively impact heat dosimetry and clinical planning.
Journal ArticleDOI
Real-time in vivo monitoring of magnetic nanoparticles in the bloodstream by AC biosusceptometry.
André G. Próspero,Caio C. Quini,Andris F. Bakuzis,Patrícia Fidelis-de-Oliveira,Gustavo M. Moretto,Fábio P. F. Mello,Marcos F.F. Calabresi,Ronaldo Vitor Reis Matos,Ednaldo Alexandre Zandoná,Nicholas Zufelato,Ricardo Brandt de Oliveira,José Ricardo de Arruda Miranda +11 more
TL;DR: The results indicate that the ACB system may be a valuable tool for in vivo, real-time MNP monitoring that allows associations with other techniques, such as pulsatile arterial pressure and electrocardiogram recordings, helping ensuring the protocol safety, which is a fundamental step towards clinical applications.
