“…From the FT-IR results, we could see the typical CaCO 3 peak around 1401, 873 and 712 cm − 1 for both samples [ 36 ]. Only in the silica-coated sample, the Si-O-Si stretching vibration peak was observed at 1068 cm − 1 wavenumber, which shows the stable coating of silica on mag-CC surfaces [ 37 ]. Additionally, Energy-dispersive X-ray Spectroscopy (EDAX) was used to confirm coating of silica to the mag-CC surface (Fig.…”

BackgroundAntibiotics, which are the most important medication in human history, have brought global concerns due to their potential risk to human health and environment by accelerating the development of drug-resistant bacteria, and accumulating in the food chain system. Among antibiotics, oxytetracycline (OTC) is widely used in aquaculture, and its potential risk of toxicity to human by bioaccumulation has been reported. Therefore, the effective removal of OTC is highly needed.ResultsIn this study, we report bio-hybrid inorganic microparticles (apt-mag-SiCC) for efficient capturing and facile magnet-based separation of oxytetracycline (OTC). These bio-hybrid inorganic microparticles are composed of magnetic separable silica coated calcium carbonate microparticles (mag-SiCC) derived from CO2, conjugated with oxytetracycline binding aptamers (OBA). These bio-hybrid inorganic microparticles were successfully synthesized, based on the characterization data obtained by SEM, FT-IR, EDAX, BET, and CLSM. About 6 μm sized bio-hybrid inorganic microparticles showed low non-specific adsorption to OTC and other molecules, and the selective capturing towards to the OTC in both buffer and tap water. Moreover, these bio-hybrid mineral microparticles were found to be stable, even after the repeated usages, maintaining the initial capturing efficiency.ConclusionUsing the newly synthesized bio-hybrid inorganic microparticles, we could successfully capture OTC by facile magnet-based separation. With advantages of theses bio-hybrid inorganic microparticles such as easy fabrication, low-price, and environmental friendliness, this novel material could be utilized in the drinking water treatment, in vitro medicinal diagnostics, or in vitro removal of antibiotics lining out from the blood (blood purification).Electronic supplementary materialThe online version of this article (10.1186/s13036-018-0113-8) contains supplementary material, which is available to authorized users.

“…The obtained data shows that the values of Qf/Qg decrease while the values of 1/Q increase with the increasing carbon black content up to the optimum concentration 40/60 phr. Moreover, the lowest values of Qf/Qg and the highest ones for 1/Q designate that, the higher the filler content, the stronger the rubber-filler interaction 23 . Finally, the obtained data indicates that 40 CB/ 60 silica was capable of producing greater rubber-filler interaction compared to each of CB and silica separately.…”

Different contents of high abrasion furnace black filler [HAF] and white filler [silica are mixed with ethylene-propylenediene monomer rubber [EPDM] cured by the conventional sulfur system. The thermogravimetric analysis (TGA) characteristics, physico-mechanical properties and swelling measurements of the prepared samples have been investigated. EDAX analyses were done to define the chemical composition of the investigated samples and to locate the dispersion of the fillers and theirs intensity. Comparison of the black and white fillers was performed and it was found that filler incorporation into the rubber matrix was one of the major parameters that enhanced the tensile strength and swelling resistance. The hardness of the investigated samples increased with increasing the filler concentration up to 40/60 phr (part per hundred parts of rubber). This increase can be attributed to greater and more uniform dispersion of filler into the rubber system. Carbon/silica are extensively used in the industry as cheapening filler with high reinforcing effect. Finally, the addition of precipitated silica at the expanse of toxic carbon black (CB) is the main step in decreasing the health risk associated with the presence of CB-filled EPDM composites.
