“…When HAP‐including vesicles were discharged from the osteoblast cells, ions will be stored and bone mimetic crystallites will develop . Graphene and HAP nanoparticles can self‐assemble into 3D nanocomposite hydrogel in view of colloidal chemistry amalgamation, utilizing fluid suspensions of GO nanosheets and citrate‐stabilized HAP nanoparticles . Amid hydrothermal treatment, thickness of GO nanosheets increases, as they pull in each other through π–π cooperation, in view of the expanded hydrophobicity.…”

Graphene and its composite materials are very important in many disciplines of science and have been used enormously by researchers since their discovery in 2004. These are a new group of compounds, and are also wonderful model systems for quantum behavior studies. Their properties like exceptional conductivity, biocompatibility, surface area, mechanical strength, and thermal properties make them rising stars in the scientific community. Graphene and its composite compounds are utilized widely in different medical applications, for example, biosensing of biological compounds responsible for disease development, bioimaging of various cells, tissues, microorganisms, animal models, etc. In addition, they are used for enhancing and supporting the stem cell differentiation, i.e., regenerative medicine for regeneration studies of various human organs, tissue engineering in biology for the development of carrier materials, as well as in bone reformation. This review focuses on the modification procedure involved in the fabrication of graphene‐based biomaterials for various applications and recent developments in research related to graphene and graphene‐based materials in biosensing, optical sensing, gas sensing, drug, gene, protein delivery, tissue engineering, and bioimaging. In addition, the potential toxicological effects of graphene‐based biomaterials are discussed.

“…The specific surface area of 0.5% Pt‐functionalized TiO 2 has increased when comparing with that of pure TiO 2 , for the specific surface area is calculated to be 168.10 and 147.17 m 2 g −1 , respectively. The numeric values are higher than that of ZnO, SnO 2 , and Fe 2 O 3 materials as gas‐sensing materials reported in other literature . This might be a point to explain the reason why 0.5% Pt‐functionalized TiO 2 based gas sensor shows more superior gas‐sensing performance than pure TiO 2 .…”

A facile hydrothermal method is used to prepare Pt-functionalized nanoporous TiO 2 nanoparticles. These are used as gas-sensing material in sensors, fabricated according to the indirect heating method. Gas-sensing performance of the sensors is investigated by testing their gas response to acetone, which exhibits favorable selectivity, good gas response value, fast response/recovery time, low detection concentration and good long-term stability to acetone. Gas response β was defined as the ratio of R a /R g , where R a and R g are the resistance values of gas sensor exposed in air and objective gas, respectively. Among all these as-prepared gas sensors, the 0.5% Pt-functionalized TiO 2 based gas sensor shows the highest gas response value of 29.51-200 ppm acetone at 300 C, and the gas response value is 5.2 times higher than that (5.67) of pure TiO 2 based gas sensor. It also has excellent selectivity to acetone when comparing with toluene, n-butanol, isopropanol, ethanol, and methanol. The large specific surface area (168.101 m 2 g À1 ) provides enough contacting interface between gas and the as-prepared materials, then the gas molecules could be broken into CO 2 and H 2 O by the active adsorbed oxygen species. The present results of the Ptfunctionalized TiO 2 based gas sensors illustrates their potential application in detecting acetone.

“…This relationship can be explained from the competition between the surface reaction and Knudsen diffusion 35 that has already been demonstrated in some of our previous reports. 36,37 Fig. 4(a-c) shows the resistance curves of the sensor to various concentration of H 2 S under different temperatures.…”
