Summary: Single-molecule potentiometers based on ortho-pentaphenylene derivatives exhibit a controllable conductance modulation through multiple folded conformers, achieving a significantly higher switching factor than previously reported values. The charge transport mechanism for these folded molecules is rationalized as a multichannel conductance governed by through-space and through-bond conducting pathways, shedding light on exploring robust single-molecule potentiometers based on helical structures.

Summary: Analytical results for the steady-state properties of the single-molecule tunneling junction are obtained using classical master equations, considering the spin-less model with one electronic level of the bridge molecule coupled to a classical harmonic oscillator. Relations between different average values are established based on these equations, with comparisons to numerically exact calculations showing good agreement. Approximate solutions for the diabatic regime are suggested, introducing effective temperature and enabling simple calculations of average vibrational excitations and tunnel current. The properties of the tunneling junction in both diabatic and adiabatic regimes are discussed, with analytical expressions derived and compared to literature results. Dependencies on reorganization energy and the position of the electronic level of the bridge molecule are also examined.

Summary: This study investigates the potential of proton transfer reactions as a fundamental mechanism to realize a nanoscale molecular transistor. By controlling the location of protons in the molecular bridge and applying an electrostatic gate field, specific conductance states can be selected in molecule-graphene nanojunctions, allowing the current in the junction to be switched on and off like in a field-effect transistor. The underlying mechanism is analyzed in detail.

Summary: We demonstrated for the first time that alpha-syn PFF spreads from BMVECs to pericytes through tunneling nanotubes (TNTs) and myosin. Inhibition of myosin 1d (Myo1d) can prevent the transfer of alpha-syn PFF from BMVECs to pericytes. Targeting Myo1d may be a promising approach to prevent the spreading of alpha-syn from blood to the brain.

Summary: Researchers report a large kinetic isotope effect (KIE) for intramolecular charge transport in p-conjugated oligophenyleneimine (OPI) molecules connected to Au electrodes. Isotopic labeling in long OPI wires (>4 nm in length) produces a conductance KIE, suggesting a thermally assisted, through-barrier polaron tunneling mechanism. Shorter OPI wires (<4 nm) do not exhibit a conductance KIE, implying a direct tunneling mechanism. Temperature-dependent measurements reveal an activated conductance for N-15-substituted OPI wires. This observation opens up opportunities for understanding microscopic conduction mechanisms in pi-conjugated molecules.

Summary: The study synthesizes a flexible and conductive ionogel electrode and uses it as a top contact to form highly reproducible protein junctions. The junctions of proteins show temperature-independent electron tunneling characteristics in solid states, but exhibit temperature-dependent electron hopping when hydrated under physiologically relevant conditions. The solvent reorganization energy is found to play an important role in the electron-hopping process and requires approximate to 100 meV for electron hopping through one heme group inside a hydrated protein molecule connected between two electrodes.

Summary: This study focuses on the significance of intermolecular charge transport in electronics and biochemical systems. By designing supramolecular dimer structures, the effects of charge state and energy level on charge transport under nanoconfinement are investigated. It is found that thermally-induced vibrations enhance incoherent tunneling in positively charged systems and the transition between coherent and incoherent tunneling is associated with specific molecular vibration modes.

Summary: The thermal instability of silver nanowires leads to increased electrical resistance in AgNW networks. Understanding the relationship between structural and electrical properties of AgNW networks is crucial for their integration as transparent electrodes in flexible optoelectronics. In situ X-ray diffraction measurements were used to study the crystallographic evolution of Ag-specific Bragg peaks during thermal ramping, revealing differences in thermal and structural transitions between bare and SnO2-coated AgNW networks.

Additionally, it could be used as a freestanding electrode in flexible devices at different bending angles.

Summary: Photodynamic therapy (PDT) is a promising local treatment modality in cancer therapy, but its therapeutic efficacy is restricted by ineffective delivery of photosensitizers and tumor hypoxia. In this study, a phototactic Chlorella-based near-infrared (NIR) driven green affording-oxygen microrobot system was developed for enhanced PDT. The system exhibited desirable phototaxis and continuous oxygen generation, leading to the inhibition of tumor growth in mice. This study demonstrates the potential of using a light-driven green affording-oxygen microrobot to enhance photodynamic therapy.

Summary: This study demonstrates a simple and environmentally-friendly method for the synthesis of zinc oxide nanozymes (ZnO NZs) using wasted hop extract (WHE). The WHE-ZnO NZs exhibit exceptional peroxidase-like activity and serve as effective catalysts for the oxidation of 3,3,5,5-tetramethylbenzidine (TMB) in the presence of hydrogen peroxide (H2O2). In addition, a straightforward colorimetric technique for detecting both H2O2 and glucose was developed using the WHE-ZnO NZs as peroxidase-like catalysts.
