Development of "on-demand" thermo-responsive hydrogels for anti-cancer drugs sustained release: Rational design, in silico prediction and in vitro validation in colon cancer models
Carreño, Gustavo; Pereira, Alfredo; Marican, Adolfo; Andrade, Fernanda; Roca-Melendres, Maria Merce; Valdés, Oscar; Vijayakumar, Sekar; Schwartz, Simo, Jr.; Abasolo, Ibane; Rafael, Diana; Duran-Lara, Esteban F.; Avila-Salas, Fabian [Univ Mayor, Fac Ciencias, Ctr Nanotecnol Aplicada, Chile] (ELSEVIER, 2021-12)A rational design accurate based on the use of Statistical Design of the Experiments (DoE) and Molecular Dynamics Simulations Studies allows the prediction and the understanding of thermo-responsive hydrogels prepared ... -
Film Dressings Based on Hydrogels: Simultaneous and Sustained-Release of Bioactive Compounds with Wound Healing Properties
Avila-Salas, Fabián [Univ Mayor, Ctr Nanotecnol Aplicada, Fac Ciencias]; Marican, Adolfo; Pinochet, Soledad; Carreno, Gustavo; Valdés, Oscar; Venegas, Bernardo; Donoso, Wendy; Cabrera-Barjas, Gustavo; Vijayakumar, Sekar; Durán-Lara, Esteban F. (MDPI, 2019)This research proposes the rational modeling, synthesis and evaluation of film dressing hydrogels based on polyvinyl alcohol crosslinked with 20 different kinds of dicarboxylic acids. These formulations would allow the ... -
Polyaniline Based Materials as a Method to Eliminate Haloanisoles in Spirits Beverages
Avila-Salas, Fabián [Univ Mayor, Fac Ciencias, Ctr Nanotecnol Aplicada]; Valdés, Oscar; Marican, Adolfo; Ignacio Castro, Ricardo; Amalraj, John; Felipe Laurie, V; Santos, Leonardo S. (AMER CHEMICAL SOC, 2018)In this research, the abilities of two polyaniline-based materials (PANI-EB and PANI-ES) were evaluated as potential fining agents to eliminate 2,4,6-trichloroanisole (TCA) and 2,4,6-tribromoanisole (TBA). The results ... -
Utilization of industrial by-product fungal biomass from Aspergillus niger and Fusarium culmorum to obtain biosorbents for removal of pesticide and metal ions from aqueous solutions
Cabrera-Barjas, Gustavo; Gallardo, Francisco; Nesic, Aleksandra; Taboada, Edelio; Marican, Adolfo; Mirabal-Gallardo, Yaneris; Delgado, Nacarid; Armas-Ricard, Merly de; Valdés, Oscar; Avila-Salas, Fabián [Univ Mayor, Fac Ciencias, Ctr Nanotecnol Aplicada, Chile] (Chile. Universidad Mayor, 2020)In this work, Aspergillus niger and Fusarium culmorum cell wall by-products were chosen as microbial sources for chitin and chitosan production. Both polysaccharides were characterized by FTIR and C-13-CPMAS NMR, but GPC ...
