“…This observation is in agreement with Feng et al [ 46 ] who also reported that the addition of graphene sheets changes the ZnO morphology from micrometre rods to nanoparticles. In fact, the oxygenated groups present on the GO surface increase the nucleation sites to anchor the Zn 2+ ions by chemical coordination, as already observed in other studies with ZnO [ 47 ] but also in other metal oxides such as TiO 2 [ 48 ]. Consequently, the availability of Zn 2+ ions to the ZnO particle growth is decreased, which enables to a reduction of their size [ 49 ].…”

The diversity of zinc oxide (ZnO) particles and derived composites applications is highly dependent on their structure, size, morphology, defect amounts, and/or presence of dopant molecules. In this work, ZnO nanostructures are grown in situ on graphene oxide (GO) sheets by an easily implementable solvothermal method with simultaneous reduction of GO. The effect of two zinc precursors (zinc acetate (ZA) and zinc acetate dihydrate (ZAD)), NaOH concentration (0.5, 1 or 2 M), and concentration (1 and 12.5 mg/mL) and pH (pH = 1, 4, 8, and 12) of GO suspension were evaluated. While the ZnO particle morphology shows to be precursor dependent, the average particle size length decreases with lower NaOH concentration, as well as with the addition of a higher basicity and concentration of GO suspension. A lowered band gap and a higher specific surface area are obtained from the ZnO composites with higher amounts of GO suspension. Otherwise, the low concentration and the higher pH of GO suspension induce more lattice defects on the ZnO crystal structure. The role of the different condition parameters on the ZnO nanostructures and their interaction with graphene sheets was observed to tune the ZnO–rGO nanofiller properties for photocatalytic and antimicrobial activities.

“…All these carbon nanomaterials display specific morphology, size, and reactivity; thus the resulting physico-chemical properties vary greatly from one another. Despite the vast literature on the topic, it is not always straightforward to anticipate which is the most suited for a specific application, especially in the complex context of biologically-relevant samples [ 43 , 44 , 45 ], or when interacting with biomolecules [ 46 ]. Nevertheless, it is possible to state that they all generally feature good electronic conductivity, low density, high mechanical strength, and the ability to be chemically functionalized to tailor their properties as required for the intended use [ 47 ].…”

Carbon nanomaterials include diverse structures and morphologies, such as fullerenes, nano-onions, nanodots, nanodiamonds, nanohorns, nanotubes, and graphene-based materials. They have attracted great interest in medicine for their high innovative potential, owing to their unique electronic and mechanical properties. In this review, we describe the most recent advancements in their inclusion in hydrogels to yield smart systems that can respond to a variety of stimuli. In particular, we focus on graphene and carbon nanotubes, for applications that span from sensing and wearable electronics to drug delivery and tissue engineering.

“…All these diverse carbon nanostructures have been widely studied, yet it is not straightforward to predict which is the ideal candidate based on the type of intended application. This challenge is amplified in biologically relevant contexts, which are characterized by a high-level of chemical complexity [ 63 , 64 , 65 , 66 , 67 ]. To this end, it is key to study their different ability to interact with biomolecules and develop a protein corona on their surface [ 68 ] that will influence their ability to elicit an immune response [ 69 , 70 ], as well as their biodegradation [ 71 , 72 ] and biodistribution [ 73 ].…”
