Protein-Graphene Interaction Analysis


At present, graphene materials have attracted widespread attention in the field of biomedicine due to their excellent physical and chemical properties and broad application prospects. When graphene materials are used in biological applications (such as drug delivery, biosensing, and bioimaging), they will inevitably interact with various proteins and cause changes in their characteristics as well as protein configuration and function. This process is considered to be the beginning of graphene materials entering the living system.

Therefore, a lot of studies have been carried out on the interaction between graphene materials and protein molecules, which can help us analyze the sites and mechanisms of the interactions at the molecular level, this is of great significance for assessing its potential toxicity in living systems, and provides an extremely important basis and guidance for the design and development of high-efficiency non-toxic graphene materials.

Creative Proteomics provides conventional analysis methods including infrared (IR) spectroscopy, photoluminescence (PL) spectroscopy, electrochemical methods and calculation methods including molecular dynamics simulations to help customers study protein-graphene interactions.

At the same time, we also provide quartz-crystal microbalance with dissipation monitoring (QCM-D), which is an evaluation method that can provide qualitative information (including the dynamics and structural properties of bound proteins). QCM-D is a real-time monitoring system based on the piezoelectric properties of AT-cut quartz crystals. Real-time monitoring of changes in resonant frequency and damping with high resolution can analyze the mass adsorption, adsorption mechanism, thickness, and structural conformation of biomolecules on the crystal surface. This novel platform can be used to monitor biochemical events, as well as an effective way to develop graphene-based biosensors.

Customers can choose a certain technology according to the needs of the project, or contact us directly for consultation, and our expert team will provide you with a customized experimental program.
