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 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 [...]
