The preparation of molecular, non-polymeric, nanogels from a low molecular weight hydrogelator is reported. Molecular
nanogels are expected to overcome issues associated with the use of polymeric nanogels in biomedicine such as
biodegradability, stimuli responsiveness, polydispersity, and batch-to-batch reproducibility. Nanogels formed by compound
1 were reproducibly prepared by sonication of a xerogel in PBS, with a total concentration of ca. 2 mM. Intensity averaged
diameter of ca. 200 nm was determined by DLS. Electron microscopy (TEM and cryo-TEM) revealed spherical particles. Light
scattering (SALS) indicates that water is the main component of the nanoparticles, being the concentration of 1 in the
nanogels of ca. 3 mg/mL. These particles can be considered to constitute an intermediate state between free molecules and
self-assembled fibrillar networks. The nanogels present excellent temporal and thermal stability and accessible hydrophobic
domains, as demonstrated by the incorporation of the fluorescent dye Nile Red. [-]
