Increased Plant Growth with Hematite Nanoparticle Fertilizer Drop and Determining Nanoparticle Uptake in Plants Using Multimodal Approach

<div>Hyperspectral imaging of black bean leaf samples. (a) Image of control DI water-treated leaf. (b) Image of leaf from a plant treated with a high concentration of hematite NPs (1.1 gL<sup>-1</sup> Fe); the red dots indicate the localization of NPs. (c) Comparative spectral plots of leaves from control and NP-treated plants.</div>
