DNA Switches: From Principles to Applications

DNA Switches: From Principles to Applications

Switched on: The stimuli-triggered reversible reconfiguration of i-motifs, G-quadruplexes, and duplex DNA structures, and of DNA devices, such as tweezers, nanosprings or walkers, are the basis for DNA switches that can be triggered by changes in pH values, metal ions/ligands, and photonic or electrochemical signals. Applications of DNA switches include controlled drug delivery, opening/closure of pores, and switchable catalysis.

Covalent Attachment of Cyclic TAT Peptides to GFP Results in Protein Delivery into Live Cells with Immediate Bioavailability

Covalent Attachment of Cyclic TAT Peptides to GFP Results in Protein Delivery into Live Cells with Immediate Bioavailability

Cycle trip: The conjugation of cyclic cell penetrating peptides (CPPs) to full-length GFP enables direct protein transport into the cell. The cyclic-CPP–GFP conjugates are internalized into live cells with immediate bioavailability, whereas linear CPP analogues are not efficient for GFP transduction. This technology expands the application of cyclic CPPs to the efficient transport of functional full-length proteins into live cells.

Indicator Displacement Assays Inside Live Cells

Indicator Displacement Assays Inside Live Cells

Live coverage: Macrocyclic host–dye complexes can be used to detect the presence of an analyte inside live cells through dye displacement. p-Sulfonatocalix[4]arene (CX4) and the fluorescent dye lucigenine (LCG, yellow) are both taken up into CHO and V79 cells to form a weakly fluorescent CX4–LCG complex in the cytoplasm. Subsequent addition of the corresponding analytes (acetylcholine, choline, and protamine; green) results in a clear increase in fluorescence.

Single-Molecule Imaging Reveals that Small Amyloid-β1–42 Oligomers Interact with the Cellular Prion Protein (PrPC)

Small oligomers bind PrPC: TIRF microscopy and a single-particle tracking approach have determined that amyloid-β peptide oligomers (oAβ) interact with the cellular prion protein (PrPC) on live neuronal cells. Having dissected this interaction at the single-molecule level, we estimate that predominantly small oAβ42 species (dimers and trimers) bind to PrPC.

Discovery of a Highly Selective PLD2 Inhibitor (ML395): A New Probe with Improved Physiochemical Properties and Broad-Spectrum Antiviral Activity against Influenza Strains

PLD2, viral killer! Focused optimization efforts led to the development of ML395, a potent (IC50=360 nM) and >80-fold selective phospholipase D2 (PLD2) inhibitor with improved physiochemical properties, no cytotoxicity, high CNS penetration and a favorable DMPK profile. The PLD2 inhibitors displayed pan-anti-influenza activity across various influenza strains (H1N1, H3N2, H5N1, H7N9).

Understanding Quantum Confinement of Charge Carriers in Layered 2D Hybrid Perovskites

Understanding Quantum Confinement of Charge Carriers in Layered 2D Hybrid Perovskites

Form a band: Quantum confinement of charge carriers in 2D hybrid perovskites is investigated, starting with the concepts of effective mass and quantum wells. For ultrathin layers, the effective-mass model fails. An alternative approach in which these perovskites are treated as composite materials is suggested, including band-offset calculations. CB=conduction band, VB=valence band.

Drug Screening Boosted by Hyperpolarized Long-Lived States in NMR

Drug Screening Boosted by Hyperpolarized Long-Lived States in NMR

Spy ligands tagged to support hyperpolarized long-lived states provide enhanced ligand binding contrast in NMR screening experiments. The binding of a stronger ligand can be monitored by displacement of the spy. These new advances broaden the applicability of the method to a wider variety of systems and also decrease ligand and protein reagent requirements.

Dimeric Tetrathiafulvalene Linked to pseudo-ortho-[2.2]Paracyclophane: Chiral Electrochromic Properties and Use as a Chiral Dopant

Chiral electrochromic properties: The synthesis and electrochromic (EC) chiroptical properties of chiral pseudo-ortho-[2.2]paracyclophane with tetrathiafulvalene units are reported. They exhibited pronounced EC properties in various redox states. Each enantiomer was examined as a chiral dopant for nematic liquid crystals (LCs), and the induced helicity of the LC solvent was in accord with the molecular chirality.

Tuning the Mechanical and Adsorption Properties of Silica with Graphene Oxide

Get set, GO! Silica/graphene oxide (GO) composite powders of various compositions have been synthesized and compacted by spark plasma sintering. The optical and mechanical properties of silica were tuned by varying the GO content (see figure). Improved fracture toughness occurred with increasing amount of GO. Powders were also applied to Cu removal from water; the adsorption properties of silica were improved with a high concentration of GO.

Lithium–Air Oxygen Shuttle Battery with a ZrO2-Based Ion-Conducting Oxide Electrolyte

Lithium–Air Oxygen Shuttle Battery with a ZrO2-Based Ion-Conducting Oxide Electrolyte

Full of hot air! A lithium–air cell based on the concept of an “oxygen shuttle” in a calcium-stabilized ZrO2 (CSZ) electrolyte is described. The observed open-circuit voltage and discharge capacity are 1.81 V and 2179 mAh per gram of Li, respectively, at 1073 K (see picture). The observed overpotential in the anode is similar to that in a Mg–air cell reported previously, and much smaller than that of a H2–air fuel cell.

Au–Co3O4/C as an Efficient Electrocatalyst for the Oxygen Evolution Reaction

Au–Co3O4/C as an Efficient Electrocatalyst for the Oxygen Evolution Reaction

What a bind! The electron binding energy of Co 2p shows a positive shift of about 0.89 eV after loading with Au (see figure). Such a big shift in binding energy promotes the formation of CoIV and increases the population of active centers on the catalyst surface. Gold, a highly electronegative metal, acts as an electron adsorbate, which facilitates the deprotonation of the OOH species by an electron inductive effect.
