Aluminum Oxide Nanoparticles Hinder Growth: Study

(A study involving tobacco plants exposed to varying levels of aluminum oxide nanoparticles reveals troubling growth issues. -ed)

Effects of Aluminum Oxide Nanoparticles on the Growth, Development, and microRNA Expression of Tobacco (Nicotiana tabacum)

"In this experiment, aluminum oxide nanoparticles affect the amount of leaves three week old tobacco seedlings have"


Nanoparticles are a class of newly emerging environmental pollutions. To date, few experiments have been conducted to investigate the effect nanoparticles may have on plant growth and development. It is important to study the effects nanoparticles have on plants because they are stationary organisms that cannot move away from environmental stresses like animals can, therefore they must overcome these stresses by molecular routes such as altering gene expression.  (Image of aluminum oxide nanoparticles at left from US Research Nanomaterials Inc.)
After three weeks of culture, the seedlings grown in the presence of aluminum oxide nanoparticles showed an obvious decrease through the visualization of the root lengths, leaf count, and biomasses of the seedlings.
