Antimicrobial polymer composites with copper micro- and nanoparticles: Effect of particle size and polymer matrix

Palza Cordero, Humberto; Quijada Abarca, Juan; Delgado, Katherine (SAGE, 2015)

The addition of metal particles, for instance, silver or copper, into polymer matrices is a relevant strategy producing novel antimicrobial materials. By using two particles with diameters around 10nm and 45 mu m, and ...

In situ antimicrobial behavior of materials with copper-based additives in a hospital environment

Palza Cordero, Humberto; Nuñez, Mauricio; Bastías, Roberto; Delgado, Katherine (Elsevier, 2018)

Copper and its alloys are effective antimicrobial surface materials in the laboratory and in clinical trials. Copper has been used in the healthcare setting to reduce environmental contamination, and thus prevent healt ...

Synthesis of copper nanostructures on silica-based particles for antimicrobial organic coatings

Palza Cordero, Humberto; Delgado, Katherine; Curotto, Nicolás (Elsevier, 2015)

Sol-gel based silica nanoparticles of 100 nm were used to interact with copper ions from the dissolution of CuCl2 allowing the synthesis of paratacamite (Cu-2(OH)(3)Cl) nanocrystals of around 20 nm. The method produced ...

Toward Tailor-Made Biocide Materials Based on Poly(propylene)/Copper Nanoparticles

Palza Cordero, Humberto; Gutiérrez, Sebastián; Delgado, Katherine; Salazar, Oriana; Fuenzalida Escobar, Víctor; Avila, Jonathan I.; Figueroa, Guillermo; Quijada Abarca, Juan (Wiley InterScience, 2010)

A set of poly(propylene) composites containing different amounts of copper nanoparticles (CNP) were prepared by the melt mixed method and their antimicrobial behavior was quantitatively studied. The time needed to reduce ...
