Brazilian university using nano technology to prevent fungi on bamboo
Mar. 29, 2017
The Department of Chemistry at the Scientific Technical Center of the Pontifical Catholic University of Rio de Janeiro, Brazil has developed a pioneering technology that uses nano particles of silver to combat fungi and bacteria in bamboo.
The goal of the research is to create a more effective control of diseases and increase the durability of plants against the natural action of biodegradation, especially in conditions of high humidity.
The scientists use a microtomograph of X- rays to help characterize the deposition of nano particles of silver in the biological matrix of bamboo. The results point out that the use of this technology impedes the multiplication of fungi, offering a good alternative for traditional chemical control.
With high humidity, this vegetable species (used as more sustainable alternative to wood for reforestation purposes) grows in approximately two months. The study “Bamboo in a Sustainable Engineer” demonstrated that the use of silver nano particles delays this procedure to no less than one year.
According to one of the heads of the research, Professor Omar Pandoli, the microtomograph of x-rays allows a visualization of the internal structure in three dimensions. The study will continue this year and will be financed by the Brazilian government through the Ministry of Science, Technology and Innovation.
Due to more sustainable option for reforestation woods, bamboo is increasingly used in civil constructions and different types of objects, both in Brazil and in other countries. However, the plant is constantly being threatened by fungi and other pests, which is damaging a $14 billion-a-year market, according to the International Network for Bamboo and Rattan (INBAR).
