Abstract
Metallo-oxide (MO)-based bioinorganic nanocomposites promise unique structures, physicochemical properties, and novel biochemical functionalities, and within the past decade, investment in research on materials such as ZnO, TiO2, SiO2, and GeO2 has significantly increased. Besides traditional approaches, the synthesis, shaping, structural patterning, and postprocessing chemical functionalization of the materials surface is inspired by strategies which mimic processes in nature. Would such materials deliver new technologies? Answering this question requires the merging of historical knowledge and current research from different fields of science. Practically, we need an effective defragmentation of the research area. From our perspective, the superficial accounting of material properties, chemistry of the surfaces, and the behavior of biomolecules next to such surfaces is a problem. This is particularly of concern when we wish to bridge between technologies in vitro and biotechnologies in vivo. Further, be...

Abstract Recently, the potential use of biomimetic silica as smart matrices for the auto-encapsulation and controlled release of functional proteins has gained increased interest because of the mild synthesis conditions. Inspired by biological silicification, in this study, we studied novel silica-forming peptides (SFPs), Volp1 and Salp1, to mediate the generation of silica hybrids in vitro . The fusion of SFPs to model fluorescent proteins directed their auto-encapsulation in wet sol-gel silica...

Compared with noble metals, semiconductors have been gradually exploited more as another type of SERS substrate materials due to their distinctive advantages. However, an inferior enhancement factor (EF) is a fatal weakness of the semiconductors. So, we combined the strong LSPR coupling between Ag particles and the charge transport channels induced by Mg doping to create a high performance SERS substrate. These magnesium-doped zinc oxide–Ag nanoparticles (ZMOA) exhibited 18 times higher SERS enh...

Controlled modification of the semiconductor surface work function is of fundamental importance for improvements in the efficiency of (opto-)electronic devices. Binding amino acids to a semiconductor surface through their common carboxylic group offers a versatile tool for modulation of surface properties by the choice of their side chain. This approach is demonstrated here by tailoring the surface work function of indium tin oxide, one of the most abundant transparent electrodes in organic opto...

Abstract The benefits of associating biological polymers with nanomaterials within functional bionanocomposite hydrogels have already been evidenced both in vitro and in vivo . However their development as effective biomaterials requires to understand and tune the interactions at the cell–protein–mineral ternary interface. With this purpose, we have studied here the impact of silica (nano)rods on the structural and rheological properties of type I collagen hydrogels ​and on the behavior of human...

We show that the azamacrocycle ‘cyclam’ (1,4,8,11-tetraazacyclodecane) in conjunction with a silicon catecholate ion generates novel hollow tetragonal tube-like crystalline materials [(C6H4O2)3Si][C10H26N4]·H2O, whose dimensions can be tuned according to the pH of the reaction medium. The synthesis approach was successful for both silicon and germanium and we hypothesise that a range of other catecholate precursors of elements such as iron could be used to generate a large array of inorganic mat...
