DNA/RNA-Graphene Interaction Analysis


Graphene is an emerging magical material, it is an allotrope of carbon consisting of a single layer of atoms arranged in a two-dimensional honeycomb lattice. In 2004, physicists Andre Geim and Konstantin Novoselov at the University of Manchester successfully separated graphene from graphite in experiments and confirmed that it can exist alone, people's interest in this material has increased exponentially. Graphene and its derivatives exhibit many superior physical, chemical and mechanical properties due to the unique combination of crystallographic and electronic structure, and have shown attractive potential in the fields of biosensing, disease diagnosis, and drug screening, etc.

Molecules, biomolecules, polymers, and even nanoparticles can be loaded/bonded onto graphene carriers. In the past few years, the coupling of nucleic acids to graphene-based materials has attracted more attention. Because nucleic acid is stable, easy to modify, and can recognize multiple targets with high selectivity and affinity, nucleic acid-interfacial graphene can greatly improve the recognition ability and biocompatibility characteristics.

Creative Proteomics integrates internationally commonly used and emerging technologies to form a unique nucleic acid-graphene interaction research platform, and has formed a team with expertise in graphene to provide consulting and overall solutions for customers' project research. Our platform includes but is not limited to the following technologies.

  • Physical techniques

Physical techniques including transmission electron microscopy (TEM), atomic force microscopy (AFM), scanning tunneling microscopy (STM) and X-ray diffraction (XRD) can characterize the structure and chemical properties of the nucleic acid-graphene interface.

  • Optical techniques

Fluorescence is a highly sensitive technology for studying the graphene-nucleic acid biological interface. We provide fluorescence spectroscopy and fluorescence resonance energy transfer (FRET) technique.

  • Electrochemical techniques

Due to its excellent electronic conductivity and electrocatalytic activity, cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS) and electrochemiluminescence (ECL) can be used to study the nucleic acid-graphene interface.
