TL;DR: In this article, size controllable SiO2 nanoparticles synthesized by adjusting the hydrolysis-condensation time and the concentration of tetraethyl orthosilicate (TEOS) in ethanol-water solution in the presence of ammonia as a catalyst were encapsulated within resorcinol-formaldehyde polymer microspheres which were fabricated in the same ethanolwater-ammonia system.

Polydopamine-based molecular imprinting on silica-modified magnetic nanoparticles for recognition and separation of bovine hemoglobin
TL;DR: The synthesis of a polydopamine-based molecular imprinted film coating on silica-Fe(3)O(4) nanoparticles for recognition and separation of bovine hemoglobin suggests that MMIPs are suitable for the removal of high abundance of protein and the enrichment of low abundance ofprotein in proteomics.

Uniform Colloidal Spheres for (Y1−xGdx)2O3 (x = 0–1): Formation Mechanism, Compositional Impacts, and Physicochemical Properties of the Oxides
TL;DR: In this article, the growth kinetics and composition evolution of the precursor spheres were investigated in detail, and it was identified for the first time that differential nucleation occurs with regard to Y and Gd, and as a result concentration gradients exist within each precursor particle of the mixed Y/Gd system.

Magnetic iron oxide nanoparticles for biomedical applications.
TL;DR: Due to their high magnetization, superparamagnetic iron oxide nanoparticles induce an important decrease in the transverse relaxation of water protons and are, therefore, very efficient negative MRI contrast agents.
