Depending on the substrate temperature, the hydrogenation of the buffer layer graphene (BLG) on SiC(0001) can form either an insulating H-BLG (T < 500 °C) or a quasi-free-standing graphene (700 °C < T < 900 °C), which may open a route for the engineering of graphene-based devices.

Bi2Te3 nanoplates have been oxidized in the air under heating with moderate laser power. Further increase of laser power burns holes on the sample surface. Optical absorption coefficient in thin Bi–Te nanoplates (NPs) strongly depends on their stoichiometry.

A new plasmonic composite structure consisting of gold nano- particles incorporated into sucrose macrocrystals in large scale, which preserves their plasmonic nature and providing robustness in handling at the same time, is presented. As a proof-of-concept demonstration, 58% plasmonic fluorescence enhancement of green CdTe quantum dots is realized when hybridized with gold nanoparticles in sucrose macrocrystals.

Porphyrin-functionalized reduced graphene oxide with a push–pull motif has been prepared following two different approaches: A straightforward Prato reaction with sarcosine and a formyl- containing porphyrin, and a stepwise approach that involved an initial Prato cycloaddition followed by nucleophilic substitution with an appropriate porphyrin.

We demonstrate here a dual-functionalized electrochemical substrate to trigger cancer cells release based on supramolecular interactions between β-cyclodextrin (β-CD) and Fc on clinical trial used aptamer AS1411-functionalized graphene platform. Our work gives an example for label-free, multi-functionalized triggered cell release based on aptamer and β-CD/graphene-modified surface

TiO2 nanotube macrostructures have been directly fabricated by using carbon nanotube (CNT) sponges as templates. The porous structures show efficient photocatalytic activity and can be easily separated and recycled.

Wet chemical synthesis of gold nanorods can be used to obtain reproducible, robust and reusable surface enhanced Raman spectroscopy substrates of self-assembled vertically aligned gold nanorod superlattices. Yoctomole-level sensitivity was obtained for detection of D-glucose and TNT solutions.
