Journal ArticleDOI
Green synthesis of nitrogen-doped carbon dots from konjac flour with “off–on” fluorescence by Fe3+ and L-lysine for bioimaging
Xiyao Teng,Changguo Ma,Chuanjun Ge,Manqing Yan,Jiaxiang Yang,Ye Zhang,Paulo C. Morais,Hong Bi +7 more
TL;DR: Highly nitrogen-doped carbon dots are prepared by the pyrolysis of konjac flour under mild conditions followed with a simple extraction by ethanol and water and the quenched fluorescence by Fe3+ can be recovered inside the living cells.
Journal ArticleDOI
Magnetic resonance of a dextran-coated magnetic fluid intravenously administered in mice.
L.M. Lacava,Zulmira G. M. Lacava,M.F. Da Silva,O. Silva,Sacha Braun Chaves,Ricardo Bentes Azevedo,Fernando Pelegrini,C. Gansau,N. Buske,Domagoj Sabolovic,Paulo C. Morais +10 more
TL;DR: Magnetic resonance was used to investigate the kinetic disposition of magnetite nanoparticles from the blood circulation after intravenous injection of Magnetite-based dextran-coated magnetic fluid in female Swiss mice, finding the system recovers the linearity due to the demagnetizing field effect alone.
Journal ArticleDOI
Synthesis and characterization of size-controlled cobalt-ferrite-based ionic ferrofluids
Paulo C. Morais,Vijayendra K. Garg,Aderbal C. Oliveira,Luciano P. Silva,Ricardo Bentes Azevedo,A.M.L. Silva,Emília Celma de Oliveira Lima +6 more
TL;DR: In this paper, the size controlled synthesis of cobalt-ferrite nanoparticles, their passivation and peptization as stable ferrofluids, and the anomalous diffusion has been used to explain the nanoparticle size control mechanism.
Journal ArticleDOI

Villiers,Patrice N. Marche,Patrice N. Marche,Géraldine Le Duc,Stéphane Roux,Olivier Tillement,Pascal Perriat +33 more
TL;DR: New, ultrasmall nanoparticles with sizes below 5 nm have been obtained and they are promising candidates as sensitising agents for image-guided radiotherapy.
Journal ArticleDOI
Genotoxicity and inflammatory investigation in mice treated with magnetite nanoparticles surface coated with polyaspartic acid
N. Sadeghiani,L.S. Barbosa,Luciano P. Silva,Ricardo Bentes Azevedo,Paulo C. Morais,Zulmira G. M. Lacava +5 more
TL;DR: The data indicate that MNPs surface-treated with polyaspartic acid may be considered as a potential precursor of anticancer drugs.
