Assembled gold nanoparticles on nitrogen-doped graphene for ultrasensitive electrochemical detection of matrix metalloproteinase-2

Synthesis of Mn3O4 nanoparticles/nitrogen-doped graphene hybrid composite for nonenzymatic glucose sensor

“…It has been widely used as the electrode material in the electrochemical sensing. In the past decades, nitrogen-doped graphene, as a kind of novel carbon nanomaterial derived from graphene has received considerable interests due to the excellent properties, such as the widely available nitrogen sources, biocompatible C N microenvironment, the low production cost, high electrical conductivity and many chemically active sites [11]. Furthermore, the latest studies indicated that the introduction of nitrogen atoms in carbon grid of graphene not only increases the active site of adsorption for the metal nanomaterials to graphene, but also enhances the interaction between graphene and nanomaterials, and improves their catalytic activity [12].…”

One-pot synthesis of Mn3O4 nanoparticles decorated with nitrogen-doped reduced graphene oxide for sensitive nonenzymatic glucose sensing

“…Graphene (GR), a novel carbon nanomaterial with a one-atom-thick planar sheet carbon structure arranged in a two dimensional honeycomb lattice, has attracted scientists' considerable interests because of its unique high surface area, rapid electron transport capability and thermal stability [10]. In the past decades, nitrogen-doped graphene, as a kind of novel carbon nanomaterial derived from graphene has received considerable interests due to the excellent properties, such as the widely available nitrogen sources, biocompatible C-N microenvironment, low production cost, high electrical conductivity and lots of chemically active sites [11].

Highly effective photothermal chemotherapy with pH-responsive polymer-coated drug-loaded melanin-like nanoparticles

“…5 PDA-based materials were biomedically applied to biosensing, bioimaging, drug delivery, tissue engineering, theranostics, and cancer photothermal treatment. [6][7][8][9][10][11][12] Many materials such as carbon nanotubes, graphene oxide (GO) sheets, gold nanorods, and conjugated polymeric nanomaterials all exhibit considerable photothermal conversion effects. [13][14][15][16][17] However, carbon nanotubes and GO sheets have low degradability in vivo, whereas gold nanorods face the drawbacks of toxicity and high cost.…”
