Application

4-Methylumbelliferone is primarily used in synthesizing medicinal compounds and as a building block for fluorescent probes. Applications include synthesis of:
  • coumarin triazole derivatives as potential antimicrobial agents.
  • coumarin salen-based fluorescence sensors for Mg2+ detection.
  • pyranocoumarin derivatives as anti-hyperglycemic and anti-dyslipidemic agents.
  • coumarin piperazine derivatives as potential multireceptor atypical antipsychotics.
  • 4-methylumbelliferyl T-antigen as a substrate for endo-α-N-acetylgalactosaminidase.

Thiol-polystyrene (SH-PS)-capped plasmonic nanoparticles can be fabricated into free-standing, one-nanoparticle-thick superlattice sheets (termed plasmene) based on physical entanglement between ligands, which, however, suffer from irreversible dissociation in organic solvents. To address this issue, we introduce coumarin-based photo-cross-linkable moieties to the
Na+ triggered fluorescence sensors for Mg2+ detection based on a coumarin salen moiety.

Bamboo, as a pioneer vegetation, often forms forests on bare lands after catastrophic landslides. Compared to evergreen forest soil, bamboo forest soil is much more labile, with a higher percentage of microbially derived organic carbon (OC), lower molecular weight, and
