Introduction: Doxorubicin (DOX) is one of the most common drugs in cancer treatment. However, its partial solubility along with the high incidence of side effects remains a challenge to tackle. To address these issues, we designed a formulation based on graphene oxide (GO) and used it as an anticancer drug delivery system.
Methods: The physical and chemical properties of the formulation were studied using FTIR, SEM, EDX, Mapping, and XRD. Release studies in the condition were used to evaluate the pH sensitivity of drug release from nanocarriers. Other studies, including uptake assay, MTT, and apoptosis assay were carried out on the osteosarcoma cell line.
Results: release studies confirmed that the synthesized formulation provides a better payload release profile in acidic conditions, which is usually the case in the tumor site. On the OS cell line, the cytotoxicity of the DOX-loaded nanocarrier (IC50=0.293 μg/mL) and early apoptosis rate (33.80 % ) were higher in comparison to free DOX (IC50=0.472 μg/mL, and early apoptosis rate= 8.31 % ) after 48 hours.
Conclusion: In summary, our results suggest a DOX-loaded graphene oxide carrier as a potential platform for targeting cancer cells.

High throughput intracellular delivery of biological macromolecules is crucial for cell engineering, gene expression, therapeutics, diagnostics, and clinical studies; however, most existing techniques are either contact-based or have throughput limitations. Herein, we report a light-activated, contactless, high throughput photoporation method for highly efficient and viable cell transfection of more than a million cells within a minute. We fabricated reduced graphene oxide (rGO) nanoflakes that was mixed with a polydimethylsiloxane (PDMS) nanocomposite thin sheet with an area of 3 cm and a thickness of ∼600 μm.

Flexible zinc-air batteries (FZABs) present a promising solution for the next generation of power sources in wearable electronics, owing to their high energy density, cost-effectiveness, and safety. However, solid-state electrolytes for FZABs continue to face challenges related to rapid water loss and low ionic conductivity. In this study, a hydrophilic and stable tetramethylguanidine-modified graphene oxide as an additive, which is incorporated into sodium polyacrylate to develop a high-performance gel polymer electrolyte (GPE), is designed.

The global challenge of wastewater contamination, especially from persistent pollutants like radioactive isotopes and heavy metals, demands innovative purification solutions. Radioactive iodine isotopes (I and I), stemming from nuclear activities, pose serious health risks due to their mobility, bioaccumulation, and ionizing radiation, particularly impacting thyroid health. Similarly, hexavalent chromium, Cr(VI), is highly toxic and persistent in water, linked to cancer and other severe health issues.

Carbon aerogels, characterized by their high porosity and superior electrical performance, present significant potential for the development of highly sensitive pressure sensors. However, facile and cost-effective fabrication of biomass-based carbon aerogels that concurrently possess high sensitivity, high elasticity, and excellent fatigue resistance remains a formidable challenge. Herein, a piezoresistive sensor with a layered network microstructure (BCNF-rGO-CS) was successfully fabricated using bamboo nanocellulose fiber (BCNF), chitosan (CS), and graphene oxide (GO) as raw materials.
