A AuNSs@PB@Ag-Apt surface-enhanced Raman scattering (SERS) probe has been developed by embedding Prussian blue (PB) between Au core and Ag shell. The PB SERS probe illustrates strong SERS activity in the Raman silent region of 2070 cm, and has a zero background signal, ensuring high sensitivity for the detection of Staphylococcus aureus (S. aureus).

As an indispensable member of the reticular material family, metal-carbon-based organometallic frameworks (OMFs) remain largely underexplored, and no chiral OMFs (COMFs) have been reported thus far. Herein, we first report the construction of COMFs from a Pd-isocyanide OMF via nucleophilic addition to the Pd-isocyanide moiety with optically pure amines. The obtained Pd-bis(acyclic diaminocarbene) (Pd-BADC)-derived chiral OMFs display excellent applicability and can be reusable chiral catalysts to highly promote asymmetric Strecker and Suzuki-Miyaura cross-coupling reactions in a heterogeneous way.

1,4-Dibenzodiazepines, an important component of nitrogen-containing heterocycles, are widely present in drugs. Herein, we developed a photochemical radical cascade cyclization reaction of isocyanides with α-carbonyl bromides under mild conditions. A sequence of 11-alkyl-substituted 1,4-dibenzodiazepines were produced in 53%-85% yields, demonstrating excellent tolerance towards various functional groups.

Herein, we present an unprecedented electrochemical reductive cyclizative carboxylation of -vinylphenyl isocyanides with carbon dioxide achieved without the use of metal catalysts. This protocol demonstrates a broad substrate scope and good functional group tolerance, facilitating the rapid assembly of 2-oxoindolin-3-acetic acids in good to high yields with excellent regioselectivity. Furthermore, these structural motifs may have potential applications in formal synthesis of bioactive natural products.

The lily is a globally popular cut flower, and managing dormancy in lily bulblets is essential for continuous, year-round production. While nitric oxide (NO) has been shown to influence seed dormancy and germination, its role in dormancy release in lilies was previously unconfirmed. In this study, we investigated the effects of NO on dormancy release in lily bulblets using SNP and c-PTIO.
