4.2.2Graphene oxide Graphene oxide(GO) is a single layer of graphite that possesses a large specific surface area, which permits the adsorption of many different moleculesviaπ-stacking and hydrogen bonding (Sanchez et al., 2012). It has been used in electronics, energy storage, drug delivery...
However, little is known about the adverse effects of graphene on the human body and ecological environment. The purpose of our work is to make assessment on the toxicity of graphene oxide (GO) against human cell line (human bone marrow neuroblastoma cell line and human epithelial carcinoma ...
Here, we assessed the comparative interaction of three GD - graphene oxide (GO), thermally reduced GO (TRGO) and chemically reduced GO (CRGO), which significantly differ in their lateral size and functional groups density, with phenotypically different human lung cells; bronchial epithelial cells (...
Graphene oxide (GO) and carboxyl graphene (CXYG) nanoplatelet suspensions were obtained in water and culture medium. Size frequency distribution of the suspensions was determined by means of dynamic light scattering. Height, lateral dimension and shape of the nanoplatelets were determined using atomic ...
The increased application of graphene oxide (GO), a new carbon-based engineered nanomaterial, has generated a potential toxicity in humans and the environment. Previous studies have identified some dysregulated microRNAs (miRNAs), such as up-regulated mi
87]. Larger protein-coated graphene oxide nanoparticles (PCGO) (~1 μm) enter cells mainly through phagocytosis, and smaller PCGO nanoparticles (~500 nm) enter cells primarily through clathrin-mediated endocytosis [88]. GO sheets could adhere and wrap around the cell membrane, insert in the ...
Direct immune-detection of cortisol by chemiresistor graphene oxide sensor Biosensors and Bioelectronics, Volume 98, 2017, pp. 473-477 Yo-Han Kim,…, Hyun Ho Lee Facile measurement of cortisol using microchannel embedded Cu-rGO-polymer composite chemiresistive sensor Chemical Engineering and Processing...
Currently, it is still a great challenge to fabricate strain sensors with high performance and well-fitting the human body. In this work, we fabricated a close-fitting and wearable graphene textile strain sensor based on graphene textile without polymer encapsulation. The graphene oxide acts as a...
In contrast to nonpatterned sensors, the patterned sensors show enhanced sensitivity and the ability to distinguish subtle motions, such as similar phonations and 81 beats per minute of pulse rate. 展开 关键词: graphene pattern human motion monitoring layer-by-layer assembly strain sensor stretchable...
Engineered nanomaterials (such as graphene oxide, GO) have shown great potential in biomedical applications as therapeutic and imaging agents. However, little is known about their potential transformations in biological settings, which may alter their physicochemical properties and consequently hinder their ...
