“…Detonation nanodiamonds have the property to adsorb on their surface a wide variety of organic compounds and macromolecules. [37,38] This phenomenon can be ascribed to the presence on the surface of chemical functionalities, predominantly carboxylates and hydroxyls, able to interact through van der Waals, hydrogen bonding and electrostatic interactions and to the presence of hydrophobic areas. [37,39,40] The preparation of the nanodiamond supported catalysts was carried out by spontaneous absorption of the organic compound from a water solution of 1-5, synthesized as previously reported.…”

“…The nanodiamonds are known to be provided with hydrophobic graphite-like domains comprised of conjugated sp 2 carbon atoms. [19,24,25] They are also known to be able, even if they are weakly charged on their surface, to absorb a large variety of hydrophobic molecules, [37,38] likely thank to these graphite-like domains. It is plausible to hypothesize that these domains give an important contribution in the interaction with the hydrophobic tails.…”

Diamond nanoparticles are an extremely promising class of carbon‐based nanomaterials. Because of their versatility, they have an interest in a large variety of applications, however, their use in the fabrication of enzyme mimics was not previously investigated. In this study, we realized hybrid systems based on guanidinium derivatives and diamond nanoparticles by simple adsorption of the organic material on their surface. The guanidinium derivatives chosen for this study are calix[4]arenes, blocked in the cone conformation via functionalization at the lower rim with alkyl chains, and decorated with guanidinium or arginine units at the upper rim. The corresponding monofunctional counterparts were also investigated as model compounds. These materials were characterized with different experimental techniques, i.e. thermogravimetric analysis, dynamic light scattering, ζ‐potential measurements and IR/Raman spectroscopy. Their catalytic properties in the cleavage phosphodiesters were investigated by an in‐depth kinetic analysis. The whole experimental picture points to conclude that these compounds are stably adsorbed onto the nanodiamonds surface and are active in the transesterification reaction of the RNA model compound 2‐hydroxypropyl p‐nitrophenyl phosphate in water, with a notable advantage over their catalytic performances at the same concentration in solution.

In this study, core/shell‐structured mesoporous hybrid silica gel particles were synthesized for the selective adsorption of hyaluronic acid. A non‐ionic amphiphilic polymer core consisting of poly(methyl methacrylate) and poly(ethylene glycol) blocks were coated with SiO2 using the Stöber method in the presence of non‐ionic and cationic surfactants to obtain mesoporous core‐shell silica particles. The surface of silica particles was functionalized through modification of L‐aspartic acid to improve their affinity against the targeted analyte, hyaluronic acid. Physico‐chemical methods including Fourier transform infrared spectroscopy, thermal gravimetric analysis, zeta‐size measurements, and transmission‐ and scanning‐electron microscopies were utilized to evaluate the properties of core‐silica particles. The surface functionalized core/shell particles have an average size of 254.7 (±33.1) nm as confirmed by TEM analysis. The hyaluronic acid adsorption performance of the modified core‐shell silica particles was optimized through varying pH, concentration, temperature, and contact time parameters. Thermodynamic parameters were estimated by applying adsorption isotherm and kinetics models to assess the favorability of the adsorption process. The models revealed that the hyaluronic acid adsorption processes follow monolayer adsorption (Langmuir model) and chemisorption (pseudo‐second‐order kinetics) processes.
