Celis, Freddy; García, Macarena; Díaz Fleming, Guillermo; Campos Vallette, Marcelo (Sociedad Chilena de Quimica, 2017)The development of new biomaterials has gained increasing attention in the last decade. One of the most important aspects in the development of these new materials is to understand the chemical cues presents in the native ...

Vetterlein, Claudia; Vásquez Salfate, Rodrigo; Bolaños, Karen; Acosta, Gerardo A.; Guzman, Fanny; Albericio, Fernando; Celis, Freddy; Campos, Marcelo; Kogan Bocian, Marcelo; Araya, Eyleen (Elsevier, 2018-06)We studied the photothermal release of carboxyfluorescein (CF) linked to the gold surface of gold nanorods (GNRs) by two Diels-Alder adducts of different lengths (n = 4 and n = 9). The functionalized GNRs were irradiated ...

Celis, Freddy; Tirapegui, Cristian; García, Macarena; Aracena, Andrés; Aliaga, Álvaro E.; Campos Vallette, Marcelo (Soc. Chilena Química, 2020)A green ancient thread sample from a Chilean mummy turban was analyzed by plasmon-enhanced Raman scattering spectroscopy using a direct drop-colloidal method. The enhanced-Raman signals in the sample are associated with ...

Gallardo Toledo, Eduardo; Tapia Arellano, Andreas; Celis, Freddy; Sinai, Tomer; Campos, Marcelo; Kogan, Marcelo J.; Sintov, Amnon C. (Elsevier, 2020)The presence of the blood-brain barrier (BBB) limit gold nanoparticles (GNP) accumulation in central nervous system (CNS) after intravenous (IV) administration. The intranasal (IN) route has been suggested as a good strategy ...
