Summary: Flexible and stretchable biosensors are increasingly utilized for acquiring high-fidelity signals in emerging applications. Organic thin film transistors (OTFTs) are ideal candidates for flexible and stretchable biosensing due to their soft nature, amplification function, biocompatibility, functionalization ease, low cost, and device diversity. This review provides a comprehensive overview of the advancements in flexible-OTFT-based biosensors, discussing their features, functionalization strategies, applications in wearable, implantable, and portable electronics, as well as neuromorphic biointerfaces. Special attention is given to emerging stretchable organic transistors and their engineering routes for achieving stretchability, along with their implementations in e-skin and smart textiles. The remaining challenges and future opportunities in this field are also summarized.

Summary: We studied a series of thiomethyl anchored cross-conjugated molecules and their skipped-conjugated alcohol derivatives using experimental and theoretical methods. The conductance values of the cross-conjugated molecules and their skipped-conjugated partners were found to be similar. Theoretical studies revealed that the conductance of the alcohol series of compounds varied more with the tilt angle. Thermopower measurements showed that the cross-conjugated ketone molecules had a higher Seebeck coefficient compared to the alcohol derivatives, with a particularly high value for the biphenyl derivative 3a.

Summary: Four cross-conjugated molecules based on the BBO moiety were synthesized, with highly segregated HOMO and LUMO levels that could be tuned semi-autonomously through substitution. Experimental data showed significant variations in LUMO levels with increased electron-density along the 2,6-axis. Introducing relatively electron-deficient moieties led to a bathochromic shift in absorption profiles and stabilization of the LUMO.

Summary: Supramolecular electronics use noncovalent interactions like π-π and hydrogen bonding to introduce molecular assemblies into electronic devices. This research demonstrates a strategy for building electronically robust switches using two different noncovalent interactions. By compressing the junction, the single-supermolecule switch is turned ON through π-π interactions dominating the transport. Stretching the junction to form hydrogen-bonded dimers turns the switch OFF, resulting in a dramatic decrease in conductance. The study shows the potential for designing robust bistable mechanoresponsive devices for integrated circuits in microelectromechanical systems.

Summary: This paper investigates the electronic, optoelectronic, and thermoelectric properties of single diketopyrrolopyrrole molecular devices with different molecular units. The single molecular devices show a negative differential resistance effect under adjusted bias voltage, and the reasons for this effect are provided. The molecular orbital energy levels can be regulated by gate voltages for conductivity conversion. The transformation of molecular device functions in time-varying alternating current transport is discussed, and bias voltage regulation is performed for better photocurrent and analysis of thermoelectric current. These findings indicate a strong correlation between the electronic, optoelectronic, and thermoelectric properties of single molecular devices and the molecular unit-length, providing guidance for the development of molecular devices with different unit lengths.

Summary: Nitrogen doping of graphene leads to graphene heterojunctions with a tunable bandgap, suitable for various applications. In this work, atomically well-defined N-doped graphene heterojunctions were fabricated and their electronic properties were investigated. It was found that different doping numbers and positions of nitrogen atoms affected the conductance of the heterojunctions significantly. Furthermore, the insertion of nitrogen atoms into the conjugation framework of graphene stabilized the molecular orbitals and altered their relative positions to the Fermi level of the electrodes.

Summary: In this study, charge-transport experiments with bianthracene-based radicals were conducted at low temperatures. It was found that the magnetism of the diradical is preserved in solid-state devices and can be observed through Kondo resonance or inelastic electron tunneling spectroscopy. The exact molecular configuration in the junction affects the magnetic fingerprints. This research provides insights into the spin-spin interaction in solid-state devices and suggests the possibility of electrical or mechanical control.

Summary: We have demonstrated charge detection with single-electron resolution at high readout frequency using a silicon field-effect transistor integrated with double resonant circuits. The transistor, with a channel width of 10 nm, can detect a single electron at room temperature. The transistor is connected to resonant circuits composed of coupled inductors and capacitors, providing two resonance frequencies. By driving the transistor with a carrier signal at the lower resonance frequency, a small signal applied to the transistor's gate modulates the resonance condition, resulting in a reflected signal appearing near the higher resonance frequency. This operation allows for charge detection with a single-electron resolution of 3 x 10(-3) e/Hz(0.5) and a readout frequency of 200 MHz at room temperature.

Summary: The field emission properties of TiS3 nanosheets and nanoribbons synthesized from bulk titanium were investigated. The nanosheets exhibited enhanced field emission behavior with a low turn-on field and delivered a large emission current density at a relatively low applied electric field.

Summary: Thermocurrent flowing through a single-molecule device provides valuable information about its quantum properties, electronic and phononic excitation spectra, and entropy. Experimentally measuring the thermoelectric heat-to-charge conversion efficiency can help select suitable molecules for highly efficient energy conversion devices predicted by theoretical studies. A superconductor-normal metal-superconductor Josephson junction thermometer is incorporated into the single-molecule device to accurately determine the temperature bias. This device architecture enables precise thermoelectric experiments on individual molecules at millikelvin temperatures.

Summary: Creating a good contact between electrodes and graphene nanoribbons (GNRs) has been a long-standing challenge in the search for the next generation GNR-based nanoelectronics. This study successfully transfers armchair-edged GNRs grown on Au(111)/mica substrates to pre-patterned platinum electrodes, resulting in polymer-free field-effect transistor devices. The devices exhibit significantly lower resistance compared to previous reports, and density functional theory calculations show that platinum has strong coupling and higher transmission compared to graphene.
