Electrospinning of collagen with nanocapsules of PLGA for delivery of paclitaxel in drug-eluting stents

Agudelo L.M., Cornelio J.A.C., Rodriguez L.F., Ortiz I.C., Hoyos L.M., Colmenares G.J., Universidad Pontificia Bolivariana, CO

Drug-eluting stents can facilitate a drug’s release directly to the specific site, but the main difficulty with drug-eluting stents is that the initial burst of drug release can extremely affect the pharmacological action and this [...]

Microwave-assisted synthesis of bioabsorbable nanoparticles to be used as reinforcement of PLGA in biomedical applications

Colmenares G.J., Ramírez M.E., Ortiz I.C., Hoyos L.M., Universidad Pontificia Bolivariana, CO

Biodegradable polymers have been used in a large number of mass production applications such as packaging, paper coating, fibers, films and other disposable items, as well as in biomedical applications (Kalia & Avérous, 2011). The [...]

An innovative partnership for the development of nanotechnology in a developing country

Posada E., Mojica D., Hatch Indisa, CO

Colombia is a developing Latin American country which is making various efforts to enhance its human talent and generate value and prosperity based in science and advanced technology. Medellín, a pioneer city in this sense, [...]

Catalytic Oxidation of Volatile Organic Compounds

Padilla O., Gallego J., Santamaria A., University of Antioquia, CO

The volatile organic compounds (VOCs) include a set of hydrocarbons with high vapor pressure. VOCs are highly harmful to health and the environment [1]. Catalytic oxidizers are one of the rising alternatives for remove them [...]

Electroflox® Pilot plant for primary wastewater treatment of leachate

Marriaga-Cabrales N., Machuca-Martinez F., Donneys-Victoria D., Alvarez-Pugliese C.E., UNIVERSIDAD DEL VALLE, CO

Landfill leachates are liquid effluents that contain a high pollutant load and represent a serious environmental challenge for the disposal sites; Even after the useful life of a landfill, leachates continue to be generated for [...]

Fabrication and Characterization of TiO2 /ZnO Nanofibers from PVAc Electrospun Microfiber for Renewable Energy Application

Camargo Silva S.M., Muñoz-Prieto E., Gomez-Pachon E., Vera-Graziano R., Universidad Pedagogica y Tecnológica de colombia and Instituto de Investigaciones en Materiales, UNAM, CO

We report the study of titanium dioxide / zinc oxide nanofibers obtained from the calcination of precursor poly (vinyl acetate) fibers with titanium isopropoxide and zinc nanopowder, which were prepared by the electrospinning technique. The [...]

Production of Bioabsorbible Nanoparticles of Polycaprolactone by Using a Recirculating System

Colmenares G., Agudelo L., Pinal R., Hoyos L., Universidad Pontificia Bolivariana, CO

Encapsulation and controlled release of substances using polymeric nanoparticles require that these have a high reproducibility, homogeneity, and control over their properties, especially when they are to be used in medical, pharmaceutical or food applications [...]
