Although these reports demonstrated in vitro applicability of GF in tissue engineering, the bioavailability and potential toxic effects of 3D GF in living models remains unclear. Effects of soy protein and genistein on blood glucose, antioxidant enzyme activities, and lipid profile in streptozotocin-induced diabetic rats. The decline in GST levels was an effect of the overuse of enzymes to resist the oxidative stresses instigated by GF, eventually GSH concentration was increased in vital tissues. Although these methodological studies indicated the toxic effects in such animal models and were useful for research, it is really hard to relate these responses and effects to those in humans. Normal histology of the fish liver was found in the control and low dose treated groups Figure 7 i,j while degeneration of hepatocytes , pyknosis, karyolysis, and karyorrhexis in nuclei of hepatocytes and degeneration of the central vein in the liver lobule of common carp were found in the medium dose treated groups.

Heart tissues tabush normal histology in the control and low dose treated common carps Figure 7 a,bwhereas brown atrophy was found in the fish heart treated with medium dose Figure 7 c due to the deposition of pale golden brown lipofuscin granules in the heart muscle fibers. A non-biodegradable feature of GFs as implanted scaffolds was demonstrated in rat exhibiting good biocompatibility [ 29 ]. Further histological imaging revealed that GF remained within liver and kidney macrophages for 7 days without showing obvious toxicity.


A large number of in vivo studies based on histology changes of vital organs exposed to graphene have been carried out before. Find articles by Farhat Jabeen. GFs were fabricated via chemical vapor deposition CVD of graphene on a Ni tabishh template, as schematically illustrated in Figure 1 a. As is well known, it is very challenging to control the number of graphene layers, with the Ni-assisted CVD method. Although these methodological studies indicated the toxic effects in such animal models and were useful for research, it is really hard to relate these responses and effects to those in humans.

As shown, enzymatic activities generally showed variation in a dose-dependent manner. GF did not induce appreciable toxic effects in serum biochemical levels because of its different morphology, chemical structure, higher surface area, and porous architecture as compared to other graphene-based counterparts.

Tracing the Bioavailability of Three-Dimensional Graphene Foam in Biological Tissues

Irregular abnormalities in these enzymatic repairs reveal the level of oxidative 3c and defense. In terms of biochemical and blood 3v testing, values remained within standard series resulting in no morphological and metabolism changes in fish model.

Materials and Methods 3. Its levels were similar among the control and treated groups, except a slight change in the kidney tissues of the common carp at a 7 day timescale indicated a reduced activity to protect the cells against H 2 O 2 Figure 5. Also the increased bioaccumulation of NPs causes a steady rise of hepatic and renal antioxidant activities, affecting the mitochondrial respirational system [ 24 ]. I G is stronger than the 2D peak intensity: Theoretical and experimental studies.


Current knowledge on the toxicological implications and bioavailability of graphene foam GF has major uncertainties surrounding the fate and behavior of GF in exposed environments. The Ni scaffold assisted CVD process is an effective way to obtain larger grains for better quality growth and to produce GF with a controlled morphology. Find articles by Shaowei Zhang.


Biochemical and ultrastructural changes in the liver of European perch Perca fluviatilis L. Received Feb 1; Accepted Mar Synthesis routes, size, surface charge, colloidal stability, surface chemistry, tabihs water namr affect in vivo nano-formulations. Nanostructured pseudocapacitive materials decorated 3D graphene foam electrodes for next generation supercapacitors. These sections were then stained with haematoxylin and eosin. The TEM Figure 1 d,e further reveals that they are comprised of multi-layered graphene.

Additionally, GF appeared to be non-biodegradable even after 7 days of treatment. The interlayer spacing was found to be 0. CAT activity was measured using the Abei method [ 35 ].

Blood analysis of common carp exposed to GF as a function of dose level after 7 days. Next, we studied antioxidant enzyme activities before carrying out the histological analysis on the vital organs. This is probably fabish of its different 3c structure, chemical and physical morphology, and architecture, compared to those of its other graphene-based counterparts. These are generally considered the most appropriate model to evaluate the properties of toxins and their implications on a biological system.

Introduction Recent development of three-dimensional graphene foams 3D GF [ 1 ] provides an effective route to uniform dispersion of graphene in a composite matrix [ 23 ]. The porosity, grain size, and surface smoothness of three-dimensional 3D Ni foam with visible grain boundaries make it suitable for GF growth. Tabish wrote nme paper.
