Cellular uptake and biocompatibility of bismuth ferrite harmonic advanced nanoparticles

Sandrine Gerber, Solène Marcelle Françoise Marie Passemard, Davide Städler, Jean-Pierre Wolf, Stephanie Hwu, Luigi Bonacina, Daniel Rytz

Bismuth Ferrite (BFO) nanoparticles (BFO-NP) display interesting optical (nonlinear response) and magnetic properties which make them amenable for bio-oriented diagnostic applications as intra- and extra membrane contrast agents. Due to the relatively rece ...

Nonlinear optical and magnetic properties of BiFeO3 harmonic nanoparticles

Sandrine Gerber, Davide Städler, Jean-Pierre Wolf, Solène Marcelle Françoise Marie Passemard, Luigi Bonacina, Daniel Rytz

Second Harmonic Generation (SHG) from BiFeO3 nanocrystals is investigated for the first time to determine their potential as biomarkers for multiphoton imaging. Nanocrystals are produced by an auto-combustion method with 2-amino-2-hydroxymethyl-propane-1,3 ...
