“…When using a lower incident energy in the range of 15 keV, which is more typical for XFI in plants, only L-shell fluorescence of these elements can be excited, which is strongly attenuated in air and plant tissue, making it challenging to perform in vivo temporal studies of medium-Z elements. XFI thus offers clear advantages in comparison to the destructive analysis techniques of ICP-MS, in particular concerning temporal and lateral resolution, which could help for a better understanding of molecular transport in plants and will more accurately inform the risk characterization of these materials in the environment, whether introduced intentionally or incidentally. − …”

Matricaria chamomilla flowers were incubated with gold nanoparticles of different sizes ranging from 1.4 to 94 nm. After different incubation times of 6, 12, 24, and 48 h, the gold distribution in the flowers was destructively measured by inductively coupled plasma mass spectrometry (ICP-MS) and non-destructively measured by X-ray fluorescence imaging (XFI) with high lateral resolution. As a control, the biodistribution of iodine ions or iodine-containing organic molecules (iohexol) was determined, in order to demonstrate the feasibility of mapping the distribution of several elements in parallel. The results show a clear size-dependent transport of the nanoparticles. In addition, the surface chemistry also plays a decisive role in disposition. Only the 1.6 nm nanoparticles coated with acetylcysteine could be efficiently transported through the stem of the flowers into the petals. In this case, almost 80% of the nanoparticles which were found within each flower were located in the petals. The study also highlights the potential of XFI for in situ recording of in vivo analyte biodistribution.

“…Additionally, SAXS can explore interactions within the system and average correlation distances, making it a valuable tool for characterizing nanocarriers and their assemblies [88]. Moreover small-angle neutron scattering and smallangle light scattering are other techniques employed for small-angle scattering, giving valuable information about the structures of nanocarriers and their interactions within the sample environment [108].…”

Research progresses have led to the development of different kinds of nanoplatforms to deliver drugs through different biological membranes. Particularly, nanocarriers represent a precious means to treat skin pathologies, due to their capability to solubilize lipophilic and hydrophilic drugs, to control their release, and to promote their permeation through the stratum corneum barrier. A crucial point in the development of nano-delivery systems relies on their characterization, as well as in the assessment of their interaction with tissues, in order to predict their fate under in vivo administration. The size of nanoparticles, their shape, and the type of matrix can influence their biodistribution inside the skin strata and their cellular uptake. In this respect, an overview of some characterization methods employed to investigate nanoparticles intended for topical administration is presented here, namely dynamic light scattering, zeta potential, scanning and transmission electron microscopy, X-ray diffraction, atomic force microscopy, Fourier transform infrared and Raman spectroscopy. In addition, the main fluorescence methods employed to detect the in vitro nanoparticles interaction with skin cell lines, such as fluorescence-activated cell sorting or confocal imaging, are described, considering different examples of applications. Finally, recent studies on the techniques employed to determine the nanoparticle presence in the skin by ex vivo and in vivo models are reported.

“…[1][2][3][4] Nanomaterials are materials having specic physical or chemical characteristics or biological impacts that have an exterior size, internal size, or surface structure that falls within the nanoscale range. [5][6][7] More precisely, a nanostructured material is thought to have dimensions ranging from 1 to 100 nm. [8][9][10] However, in medicine, these values may vary up to a diameter of 200 nm.…”
