Iron-sequestering molecules play a pivotal role in the mechanism of toxicity of SWNTs on fungal and bacterial cells

Chaves J.S., Chaves S.J., Zuniga P., Chaves J.S., Chaves S.J., Instituto Tecnologico de Costa Rica, CR

In this study we described that iron-sequestering molecules are responsible for the toxicity of iron containing SWNTs to microorganisms. After incubating different concentrations of functionalized SWNTs with bacteria and fungal cells, it was found that [...]

A novel mechanism for the synthesis of ultra-purified silver nanoparticles for the use in biomedical materials

Zuniga P., Chaves J.S., Chaves S.J., Chaves J.S., Chaves S.J., Universidad de Costa Rica and Instituto Tecnologico de Costa Rica, CR

Biomedical products are regulated by high standards of purity and quality compared to those that are not going to be linked to the human body. So it is a real challenge to incorporate a nanotechnological [...]

A novel technique using SWCNTs to enhanced development and root growth of fig plants (Ficus carica)

Flores D., Chaves J.S., Chacón R., Schmidt A., Instituto Tecnologico de Costa Rica, CR

The overall goal of this project is to look at possible mechanisms to explain the effects of SWCNTs in plant growth and its antimicrobial properties in order to reduce the use of harmful chemicals in [...]

Novel Approach using SWCNT as a Mechanism of Toxicity on Fungal and Bacterial Cells

Chaves J.S., Chaves S.J., Chaves J.S., Chaves S.J., Instituto Tecnologico de Costa Rica, CR

The overall goal of this project was to characterize the potential use of SWNTs as an effective alternative to present antimicrobial agents in dealing with drug-resistance. In this study, we look at possible mechanisms to [...]
