Fig. 4: Detection of quantum dots in isolated chloroplasts by confocal microscopy and inductively coupled plasma mass spectrometry (ICP-MS).
From: Targeted delivery of nanomaterials with chemical cargoes in plants enabled by a biorecognition motif
a Confocal fluorescence microscopy images of isolated chloroplasts that were targeted in vivo with CdTe quantum dots functionalized with a chloroplast guiding peptide (Chl-QD). b ICP-MS elemental analysis of cadmium and tellurium in isolated chloroplasts from plant leaves exposed to Chl-QD (n = 5) and controls (n = 5) infiltrated with TES buffer. Scale bar, 50 μm. Box plot error bars represent standard deviation, boxes are the interquartile range from the first to the third quartile with squares as the medians, and horizontal line represents the mean. Statistical comparison was performed by independent samples t-test (two tailed). *** indicates P < 0.001.
