CVD graphene from UniversityWafer.com is a great substrate to use for a wide variety of biotech research. Graphene has several unique properties including DNA absorption, its function as a super quencher, and protection from enzyme cleavage which make it an ideal nanomaterial for biological engineering. Most biotech applications of graphene utilize some form of biofunctionalization. This process improves the biocompatibility, solubility, and selectivity of the graphene by bonding organic functional groups to a graphene substrate. This includes the development of things like fluorescence resonance energy transfer(FRET) biosensors developed to detect a wide range of proteins, small molecules and ions, and applications in drug delivery including the use of Graphene Oxide as a delivery vehicle for water soluble cancer drugs.
Graphene could also prove to be a valuable nanomaterial in the development of nanoscale bio-electrical interfaces due to its excellent chemical stability. However, more research needs to be done to understand the interaction of graphene with the human body, including better understanding of its potential toxicity.
Some Graphene Biotech Research Includes:
Graphene oxide has been shown to have excellent characteristics as a nanomaterial for drug delivery, including high specific surface area, and enriched oxygen containing groups, which lend GO outstanding biocompatibility, and physiological solubility, as well as loading by chemical conjugation with available reactive COOH and OH groups. This approach has implications for cancer therapy as well.
Furthering on from research done with GO as a vehicle for drug delivery more specific research has been done into its uses as a nanocarrier for non-water soluble anticancer drugs. Specific work looking into the feasibility of nanomaterial-based systems for the loading of multiple drugs has been done, since most anti-cancer approaches rely upon the use of multiple drugs to overcome the drug resistance of cancer cells. The loading of multiple drugs onto a graphene oxide substrate has been shown to improve targeting and yield much higher cytotoxicity than GO loaded with only one drug.
A variety of graphene based substrates have been studied for their potential applications in bionsensing using a wide range techniques; utilizing the fluorescence super-quenching ability of graphene to develop novel FRET biosensors, graphene’s unique electronic properties to create FET biosensors, and as a matrix for the detection of different molecules such as thrombin, ATP, amino acid, dopamine, and many others.
Graphene oxide has potential uses in bioimaging as well. Researchers have prepared smaller Graphene oxide, on the order of 10nm, called graphene quantum dots. Owing to graphene’s unique fluorescent properties this can be used for bioimaging purposes. A variety of different approaches have been used to improved to the fluorescent yield of GQD including functionalization of GQD with alkylamine. One advantage that GQDs have over II-VI QDs such as CdSe is significantly improved biocompatibility. It is also possible to utilize pH dependant optic properties of GQD to control the fluorescent response of the graphene for safe and efficient imaging.
Research has been done in the field of anti-bacterial materials using graphene. Such as a study which used a suspension of graphene oxide to develop a paper which has excellent anti-bacterial characteristics, with possible clinical applications. Other studies have been done investigating the effectiveness of graphene nanowalls deposited on stainless steel substrates against e. coli.
