Morphology modulation of silica mesoporous nano- and microparticles for atrazine - controlled release

Atrazine is a moderately toxic triazine, used as a selective pre- and post-emergence herbicide. After application, it remains in the environment due to its low biodegradability causing severe environmental effects. Several controlled release systems have been proposed in order to minimize the negati...
