A pyrene-functionalized triazole-linked hexahomotrioxacalix[3]arene as a fluorescent chemosensor for Zn²⁺ ions [PDF]
, 2016 A new pyrenyl appended hexahomotrioxacalix[3]arene L featuring 1,2,3-triazole linkers was synthesized as a fluorescent chemosensor for Zn²⁺ in mixed aqueous media. It exhibited high affinity toward Zn²⁺, and the monomer and excimer emission of the pyrene

Spectral Distortions in Metal-Enhanced Fluorescence [PDF]
Biophysical Journal, 2015 In recent years our laboratory and others have demonstrated many examples and concepts in Metal-Enhanced Fluorescence1 (MEF), a surface plasmon phenomenon, which amplifies both fluorescence and luminescence signatures in the near-field, i.e. less than one wavelength of light away from a metallic object1.

Calpain small subunit homodimerization is robust and calcium‐independent
FEBS Letters, EarlyView.Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.
