Article Synopsis
- The study examined how long exposure to zinc oxide-eugenol (ZOE) cement affects the retention of eugenol in dentin and the strength of resin composite bonds.
- The research involved testing human molars with varying exposure times and found that eugenol levels remained consistent regardless of exposure duration, while bond strength was significantly reduced when using ZOE, especially with OptiBond FL.
- Conditioning treatments using phosphoric acid or EDTA effectively lowered eugenol retention but still revealed decreased bond strength; hence, ZOE should be avoided before applying resin-based restorations.
The DNA-enabled dimerization of pentamethine cyanine (Cy5) dyes was studied by optical methods. The value of cyanine as a chiroptical reporter using a monomer-to-dimer switch is demonstrated. The specific shape of the CD signal and its high intensity are a result of J-type assembly.

High molar absorptivity, environment-sensitive fluorescence properties and intense CD effects render squaraines valuable building blocks for DNA-based optical probes and nanostructures.

Here we present a comprehensive spectroscopic study of aggregates and co-aggregates of the non-chiral Py(7) and its mono- or di-substituted nucleotide analogs (Py(7)-N and N-Py(7)-N'). The data show that the formation of supramolecular polymers from oligopyrenotides is highly sensitive to the nature of the attached, chiral auxiliary.
