Autor: Zixia Wu, Tonghe Pan, Deqing Lin, Weibo Xia, Jia Shan, Rumei Cheng, Mei Yang, Xuting Hu, Kaihui Nan, Lei Qi
Publikováno v: Journal of Materials Chemistry B. 10:3567-3576
To deal with tumor microenvironment, chemodynamic therapy has been developed, which uses nanocatalysts simulating peroxidase to convert high concentration hydrogen peroxide into toxic hydroxyl radicals in situ and effectively kills tumor cells.

Porous Graphene Oxide Films Prepared via the Breath-Figure Method: A Simple Strategy for Switching Access of Redox Species to an Electrode Surface
Autor: Susana Inês Córdoba de Torresi, Long Zhang, Liming Dai, Duyen H. T. Nguyen, Rumei Cheng, J. Justin Gooding, Vinicius R. Gonçales, Rafael N.P. Colombo, Richard D. Tilley
Publikováno v: ACS applied materialsinterfaces. 12(49)
Porous materials can be modified with physical barriers to control the transport of ions and molecules through channels via an external stimulus. Such capability has brought attention toward drug delivery, separation methods, nanofluidics, and point-

Understanding the selective-sensing mechanism of lysine by fluorescent nanosensors based on graphene quantum dots
Autor: Rumei Cheng, Shipeng Tang, Zhengan Zhen, Chunlei Yu, Shengju Ou
Publikováno v: Spectrochimica acta. Part A, Molecular and biomolecular spectroscopy. 242
The selectivity of single-amino acid nanosensors is still not well understood. Herein, the factors that govern graphene-based nanomaterials for the selective detection of lysine are reported to guide the design of single-amino acid nanosensors. Graph

Nitrogen-doped graphene quantum dots-MoS2 nanoflowers as a fluorescence sensor with an off/on switch for intracellular glutathione detection and fabrication of molecular logic gates
Autor: Chaoqun Zhou, Zhengan Zhen, Rumei Cheng, Bin Liu, Liangliang Qian, Chunlei Yu, Xiumei Cheng, Shipeng Tang
Publikováno v: Microchemical Journal. 171:106786
We designed and evaluated a high-performing and biocompatible sensing platform to quantitatively detect glutathione (GSH) in the intracellular environment. To this end, we constructed a fluorescent switch using nitrogen-doped graphene quantum dots (N

Label-Free Graphene Oxide Förster Resonance Energy Transfer Sensors for Selective Detection of Dopamine in Human Serums and Cells
Autor: Quanbin Dai, Lei Qi, Rumei Cheng, Pan Tonghe, Congcong Ge, Zhengyun Zhang, Ma Jinlei, Liming Dai, Huiying Huang
Publikováno v: The Journal of Physical Chemistry C. 122:13314-13321
A novel label-free Forster resonance energy transfer (FRET) sensor was developed from graphene oxide (GO) functionalized with doxorubicin (DOX) for selective and sensitive detection of dopamine (DA). Due to the competitive adsorption of DOX and DA on

A turn-on fluorescent lysine nanoprobe based on the use of the Alizarin Red aluminum(III) complex conjugated to graphene oxide, and its application to cellular imaging of lysine
Autor: Huiying Huang, Liming Dai, Congcong Ge, Rumei Cheng, Shengju Ou, Yu Peng, Bu Yexu, Yuhua Xue, Hongyan Liu
Publikováno v: Microchimica Acta. 184:3521-3528
The authors describe a rationally designed nanoprobe for the fluorometric determination of lysine. It is based on a ternary complex consisting of graphene oxide, aluminum ions (acting as a bridging agent), and alizarin red (GO-Al-AR). The fluorescenc

Determination of Ag+ ions by a graphene oxide based dual-output nanosensor with high selectivity
Autor: Rumei Cheng, Shengju Ou, Bu Yexu, Congcong Ge, Yuhua Xue, Lingli Li, Liming Dai
Publikováno v: RSC Advances. 6:36218-36222
A new highly selective chemosensor for Ag+ ions was designed and synthesized by covalently introducing well-known fluorophore 1,8-diaminonaphthalene (DAN) onto graphene oxide (GO) sheets. The resultant fluorescent sensor 1,8-diaminonaphthalene-graphe
