Graphene-Based Nanomaterials in Bioimaging

Selective heat generation in cancer cells using a combination of 808 nm laser irradiation and the folate-conjugated Fe2O3@Au nanocomplex

“…Recent efforts in this area have focused on the implementation of nanotechnology to improve the current efficiency of cancer diagnosis and therapy. The use of nanoprobes in association with biomedical imaging has exhibited great promise in eliminating the current detection limits of cancer diagnosis [1,2]. On the other hand, chemotherapy and radiotherapy, are the major lines of cancer therapy, have been subjected to considerable improvements through incorporation with nanomaterials [3][4][5][6][7].…”

Introductory Chapter: Nano-bioimaging—Past, Present, and Future

“…[28], the biomedical applications of graphene and its derivatives are extensively investigated for diagnostics, drug delivery, near-infrared (NIR) light-induced photothermal therapy, and bioimaging. Due to the versatile surface functionalization and ultrahigh surface area of graphene and its derivatives, they can be easily functionalized by small-molecule dyes, polymers, nanoparticles, drugs, or biomolecules to obtain graphene-based nanomaterials for different bioimaging applications [28]. Lin et al [28], focused on applying graphene-based nanomaterials for different molecular imaging modalities, and their review confirmed that the graphene-based materials can be employed for optical imaging (FL, two-photon FL, and Raman imaging), PET/SPECT (positron emission tomography/single photon emission computed tomography), MRI (magnetic resonance imaging), PAI (photoacoustic imaging),…”

Size engineering optoelectronic features of C, Si and CSi hybrid diamond-shaped quantum dots

“…Nanomaterials, especially semiconductor quantum dots (QDs), are of immense interest for bioimaging and clinical diagnosis. [1][2][3] Owing to the strong quantum connement, these small particles possess several unique properties such as, size, wavelength-dependent luminescence, and low photo-bleaching, which make them the perfect candidates for in vitro and in vivo bioimaging probes. 4,5 To fabricate graphene quantum dots, there are two main ways, namely the top-down and bottom-up approaches.…”
