Graphene Oxide: A Comparison of Reduction Methods

C – Journal of Carbon Research, Journal Year: 2023, Volume and Issue: 9(3), P. 73 - 73

Published: July 27, 2023

This paper presents a comparison of traditional thermal and chemical reduction methods with more recent ionizing radiation via gamma rays electron beams (e-beams). For GO, all synthesis protocols were adapted to increase production scale are contribution this work. The typical Raman D-band the GO was prominent (ID/IG ratio increased sixfold). When comparing techniques, dramatic differences in efficiency particle characteristics observed. Although effective methods, as shown through use FTIR spectroscopy C/O from EDS analysis, process renders great weight losses, whereas processing may involve hazardous compounds. On other hand, e-beam for 80 kGy, spectra analysis suggested that caused greater reduction: 5.4 4.1, respectively. In addition being fast effective, processes allow easier control degree by adjusting dose. dose 40 showed ID/IG ratios 15 116%,

Graphene Hybrid Tough Hydrogels with Nanostructures for Tissue Regeneration

Nano Letters, Journal Year: 2024, Volume and Issue: 24(7), P. 2188 - 2195

Published: Feb. 7, 2024

Over the past few decades, hydrogels have attracted considerable attention as promising biomedical materials. However, conventional require improved mechanical properties, such brittleness, which significantly limits their widespread use. Recently, with remarkably toughness been developed; however, low biocompatibility must be addressed. In this study, we developed a tough graphene hybrid hydrogel nanostructures. The resultant exhibited remarkable properties while representing an aligned nanostructure that resembled extracellular matrix of soft tissue. Owing to synergistic effect topographical and enhanced biochemical had excellent stretchability, resilience, toughness, biocompatibility. Furthermore, displayed outstanding tissue regeneration capabilities (e.g., skin tendons). Overall, proposed may provide significant insights into application in regeneration.

Graphene Oxide (GO) for the Treatment of Bone Cancer: A Systematic Review and Bibliometric Analysis

Nanomaterials, Journal Year: 2024, Volume and Issue: 14(2), P. 186 - 186

Published: Jan. 13, 2024

Cancer is a severe disease that, in 2022, caused more than 9.89 million deaths worldwide. One worrisome type of cancer bone cancer, such as osteosarcoma and Ewing tumors, which occur frequently infants. This study shows an active interest the use graphene oxide its derivatives therapy against cancer. We present systematic review analyzing current state art related to GO treating osteosarcoma, through evaluating existing literature. In this sense, studies focused on GO-based nanomaterials for potential applications were reviewed, has revealed that there excellent trend toward nanomaterials, based their thermal anti-cancer activities, treatment various therapeutic approaches. However, research needed develop highly efficient localized therapies. It suggested, therefore, photodynamic therapy, photothermal nanocarriers should be considered non-invasive, specific, alternatives osteosarcoma. These options promising approaches enhance effectiveness while also seeking reduce side effects minimize damage surrounding healthy tissues. The bibliometric analysis photochemical treatments reduced from January 2004 December 2022 extracted 948 documents with search strategy, mainly papers, conference demonstrating high-impact field supported by need selective central countries leading are United States, Iran, Italy, Germany, China, South Korea, Australia, strong collaborations At same time, most-cited papers published journals impact factors 6.0 (2021), 290 citations.
