Fig. 2From: Delivery of acetamiprid to tea leaves enabled by porous silica nanoparticles: efficiency, distribution and metabolism of acetamiprid in tea plantsConcentration of (1) acetamiprid and (2) dimethyl-acetamiprid in different parts of tea saplings over time when treated with (A) Ace-C or (B) Ace@MSNs. Dashed lines represent when the tea saplings were transferred to blank nutrient solution; error bar represents standard deviation (n = 6). (3) Ratio of dimethyl-acetamiprid to acetamiprid in various parts of tea tree (A3: Ace-C, B3: Ace@MSNs)Back to article page
