Supramolecular fishing for plasma membrane proteins using an ultrastable synthetic host–guest binding pair

Characterization of plasma membrane proteins is important in understanding fundamental biological processes and developing new drugs, but their separation remains a challenge. Now, a synthetic receptor–ligand pair based on ferrocene derivatives and cucurbit[7]uril is shown to have exceptionally high binding affinity, and enables membrane proteins to be isolated efficiently without any contamination from naturally biotinylated molecules.

Dark states of electrons in a quantum system with two pairs of sublattices

The identification of dark states—quantum states that do not interact with photons—in real materials may help to address many unsolved issues in condensed-matter physics. Now, they have been identified in palladium diselenide.

Ferromagnetic quasi-atomic electrons in two-dimensional electride

Ferromagnetic quasi-atomic behavior of interstitial anionic electrons (IAEs) in practical electrides is yet to be discovered experimentally. Here, the authors reveal that IAEs in two-dimensional electride [Gd₂C]²⁺⋅2e^- behave as magnetic elements with their own magnetic moment.

OrthoID: profiling dynamic proteomes through time and space using mutually orthogonal chemical tools

Proteomics at the organelle contact site remains challenging due to the spatial and temporal dynamics of proteins. Here, the authors developed OrthoID, a mutually orthogonal dual enzymatic proteomics approach to explore the proteome at the contact site of the endoplasmic reticulum and mitochondria.

Hollow nanotubular toroidal polymer microrings

Mechanically robust and shape-persistent hollow toroidal polymer microrings have been synthesized directly by thiol-ene photopolymerization of rectangular-shaped monomers with dithiols. The size of the microrings can be tuned by varying the monomer concentration. The resulting structures can encapsulate molecules in their hollow interiors and also serve as scaffolds to template the formation of circular arrays of metal nanoparticles.

Audible sound-controlled spatiotemporal patterns in out-of-equilibrium systems

Patterns formed by artificial out-of-equilibrium chemical oscillating networks (such as the Belousov–Zhabotinsky reaction) are difficult to control with any precision. Now, it has been shown that low-intensity audible sound can be used to generate spatiotemporal patterns with a programmable distribution of redox- and pH-responsive chemical systems and supramolecular assemblies in solution.

Supramolecular latching system based on ultrastable synthetic binding pairs as versatile tools for protein imaging

Although protein-ligand pairs are useful tools for bioimaging, they are susceptible to enzymatic degradation and interference from endogenous species. Here, the authors show that a synthetic and bioorthogonal cucurbit[7]uril-guest binding pair can be used to visualize proteins in cells, overcoming limitations of protein-based platforms.
