The Importance of Bioimaging

The Importance of Bioimaging

Bioimaging plays a vital role in both research and clinical practice, which makes it possible to observe and study biological processes from the cellular and subcellular level to small animals. By using specific molecular probes or contrast agents, bioimaging technology can detect and characterize early-stage disease and provide a rapid method for monitoring response to treatment. Molecular imaging modes include optical imaging, radionuclide-based imaging, MRI (magnetic resonance imaging), PAI (photoacoustic Imaging), CT (computed tomography) and multimodal imaging.

Accelerate Research and Practice of Graphene in Bioimaging

Graphene and its derivatives can be easily functionalized with small molecule dyes, polymers, nanoparticles, drugs or biomolecules due to its multi-functional surface functionalization and ultra-high surface area, so as to be suitable for different biological imaging applications of graphene-based nanomaterials. For example, GO/rGO is functionalized with dye, QD or GNC has been widely used in FL imaging research. Due to its inherent photoluminescence properties, GQD can be used as a photoluminescence probe for FL imaging. In vivo PET imaging can be performed using 64Cu-labeled nGO-PEG. NGO conjugated to trastuzumab can be used for in vivo targeting and SPECT imaging.
