Gold Nanostructures for Sensing and Functional Bioimaging

Paramagnetic gold nanostructures for dual modal bioimaging and phototherapy of cancer cells.

Paramagnetic gold nanostructures were synthesized by combining the paramagnetism of gadolinium with the plasmonic properties of gold nanoparticles and used for dual modal (MRI and optical) imaging and phototherapy of breast cancer cells.

Self-assembled Lignocellulose Micelles: a New Generation of Value-added Functional Nanostructures

Lignocellulose-based self-assembled micelles have emerged as a new generation of value-added functional nanostructures that show promise to address issues concerning the depletion of non-renewable resources; also these materials may contribute to the growing enthusiasm of utilizing biomass resources. Lignocellulose micelles can be conveniently prepared by self-assembly of amphiphilic lignocellu...

Bright three-photon luminescence from gold/silver alloyed nanostructures for bioimaging with negligible photothermal toxicity.

Simultaneous excitation and emission enhancements in upconversion luminescence using plasmonic double-resonant gold nanorods

The geometry and dimension of a gold nanorod (GNR) are optimally designed to enhance the fluorescence intensity of a lanthanide-doped upconversion nanocrystal placed in close proximity to the GNR. A systematic study of the electromagnetic interaction between the upconversion emitter of three energy levels and the GNR shows that the enhancement effect arising from localized electric field-induce...

Cytotoxity Assessment of Gold Nanoparticle-Chitosan Hydrogel Nanocomposite as an Efficient Support for Cell Immobilization: toward Sensing Application

Cell-based biosensors have become a research hotspot in biosensors and bioelectronics fields. The main feature of cell-based biosensors is the immobilization of living cell on the surface of transducers. Different types of polymers which are used as scaffolds for cell growth should be biocompatible and have reactive functional groups for further attachment of biomolecules. In this work, the cel...
