Journal ArticleDOI
Photothermal conversion efficiency and cytotoxic effect of gold nanorods stabilized with chitosan, alginate and poly(vinyl alcohol)
Mario Almada,B.H. Leal-Martínez,Natalia Hassan,Marcelo J. Kogan,María G. Burboa,Antonio Topete,Miguel A. Valdez,Josué Juárez +7 more
TL;DR: The cytotoxicity of coated gold nanorods diminished significantly compared with those GNR stabilized with CTAB, and the photothermal cellular damage of GNR systems were evaluated on a breast cancer cell line.
Journal ArticleDOI
Peptide multifunctionalized gold nanorods decrease toxicity of β-amyloid peptide in a Caenorhabditis elegans model of Alzheimer's disease.

Vásquez,Katherine Rodriguez,Macarena Sánchez-Navarro,Ernest Giralt,Eyleen Araya,Rebeca Aldunate,Marcelo J. Kogan +16 more
TL;DR: It is determined that the nanoconjugate does not affect neuronal viability; it penetrates the cells, and decreases aggregation of Aβ peptide in vitro, and it is shown that when the nanosystem is applied to a Caenorhabditis elegans AD model, the toxicity of aggregated A β peptide is decreased.
Journal ArticleDOI
Easy, Quick, and Reproducible Sonochemical Synthesis of CuO Nanoparticles
TL;DR: A monoclinic crystal system corresponding to CuO was demonstrated, and diffraction peaks were identified and confirmed according to their selected area electron diffraction (SAED) patterns.
Journal ArticleDOI
Gold nanoparticles for photothermally controlled drug release
Ariel R. Guerrero,Natalia Hassan,Carlos Escobar,Fernando Albericio,Marcelo J. Kogan,Eyleen Araya +5 more
TL;DR: This article describes how nanoparticles work in photothermally triggered drug delivery, starting with a description of the plasmon resonance and the photothermal effect, and how this is used to release a drug.
