Nitrodopamine modified MnO₂ NS-MoS₂QDs hybrid nanocomposite for the extracellular and intracellular detection of glutathione

Abstract

We have developed a highly sensitive and reliable FRET probe using nitro-dopamine (ND) and dopamine (DA) coated MnO2 nanosheet (ND@MnO2 NS and DA@MnO2 NS) as an energy acceptor and MoS2 quantum dots (QDs) as an energy donor.

Design of poly(N-isopropylacrylamide) coated MnO2 nanoparticles for thermally regulated catalytic decomposition of H2O2

“…S6†). The mechanism of surface modification of MnO 2 by nitrodopamine is elaborately discussed by Sivakumar et al , 26 as mentioned earlier. Both theoretical and experimental proofs are given to prove the attachment of catechol hydroxyl groups present in nitrodopamine to the MnO 2 surface.…”

“…A recent study from our group explained the efficient surface modification of MnO 2 nanosheets by a nitrodopamine moiety for extracellular and intracellular glutathione detection. 26 This work inspired the utilization of a thermoresponsive polymer having a nitrodopamine end group for the surface modification of MnO 2 NPs. Polymeric materials, especially thermoresponsive polymers [ e.g.…”
