Book Description
Ultrasmall nanoparticles have seen growing interest in several fields such as medicine, optics, and catalysis due to their unique size-dependent properties. Among these are fluorescent core-shell silica nanoparticles synthesized in water known as Cornell prime dots (C' dots), which are composed of a silica core and a poly(ethylene glycol) (PEG) shell. These C' dots are poised to become promising diagnostic and therapeutic tools in medicine, particularly for cancer applications. While spherical C' dots have already been in FDA-approved human clinical trials, exploration has expanded into different topologies of silica nanoparticles such as rings and cages, providing higher aspect ratios and higher surface area to volume ratios. For clinical translation of such nanostructures, quantitative assessments of their size and size dispersity remain parameters for further investigation and are critical to understanding and evaluating their effectiveness and safety in nanomedicine applications. Here, solution small-angle X-ray scattering was employed to characterize 3D structural details of ring-type silica nanostructures and their size and size dispersity. A hollow cylinder model provided consistent structural and dispersity parameters that were supported by transmission electron microscopy investigations.

Book Description
In recent years, the fabrication of nanomaterials and exploration of their properties have attracted the attention of various scientific disciplines such as biology, physics, chemistry, and engineering. Although nanoparticulate systems are of significant interest in various scientific and technological areas, there is little known about the safety of these nanoscale objects. It has now been established that the surfaces of nanoparticles are immediately covered by biomolecules (e.g. proteins, ions, and enzymes) upon their entrance into a biological medium. This interaction with the biological medium modulates the surface of the nanoparticles, conferring a “biological identity” to their surfaces (referred to as a “corona”), which determines the subsequent cellular/tissue responses. The new interface between the nanoparticles and the biological medium/proteins, called “bio-nano interface,” has been very rarely studied in detail to date, though the interest in this topic is rapidly growing. In this book, the importance of the physiochemical characteristics of nanoparticles for the properties of the protein corona is discussed in detail, followed by comprehensive descriptions of the methods for assessing the protein-nanoparticle interactions. The advantages and limitations of available corona evaluation methods (e.g. spectroscopy methods, mass spectrometry, nuclear magnetic resonance, electron microscopy, X-ray crystallography, and differential centrifugal sedimentation) are examined in detail, followed by a discussion of the possibilities for enhancing the current methods and a call for new techniques. Moreover, the advantages and disadvantages of protein-nanoparticle interaction phenomena are explored and discussed, with a focus on the biological impacts.
