Bioelectronic and biochemical signals can be remotely and optically monitored simply by a photodiode (specifically, a microscale lightemitting diode (micro-LED)), which can work as an energy receiver, a signal amplifier and an optical transmitter at the same time, based on its photon-recycling effects.

Multiple counter doping enabled threshold voltage (Vth) control for transition metal dichalcogenides (TMDCs) field-effect transistors was investigated via acceptor (or donor)-like octadecyltrichlorosilane (ODTS) (or poly-L-lysine (PLL)) treatment, respectively. Precisely controlled Vth freezing via cyclic transparent optical polymer (CYTOP) encapsulation and its counter doping effects were successfully validated. As various embodiments on practical applications, complementary inverters, active control for micro-lightemitting diode (μ-LED), and flexible device were experimentally demonstrated.

Crosstalk in polymer microelectrode arrays (MEAs) could result in non-negligible interference in the neural signal recording due to the densely packed interconnects along with the ultra-thin polymeric encapsulation/substrate layers. Here, by truly isolating the victim channel and precisely controlling its grounding condition, we systematically characterized the crosstalk in polymer microelectrodes with the aid of equivalent circuit modelling and finite element analysis.

A capacitive biopotential sensor with integrated processing electronics is demonstrated on a fabric substrate. Electrodes with a high area ratio and high dielectric constant nanoparticles greatly enhance the signal-to-noise ratio of the collected signals.

In this study, we have proposed a versatile ligand-assisted cooperative template method to synthesize multi-shelled mesoporous hollow metal hydroxide and metal oxide nanospheres. The obtained Au nanoparticles loaded nanocomposites exhibit excellent catalytic activity of hydrocarbons with sp3 C–H bonds, such as ethylbenzene with a conversion of 28.2% when the selectivity is nearly 90%.

Mesoporous resorcinol–formaldehyde nanobowls with optimized benzenoid–quinoid donor–acceptor couples have been synthesized as high-performance photocatalysts for hydrogen peroxide (H2O2) production in a sacrificial agent-free system.

This work reports an easy soft-template method to precisely engineer porous architectures of quaternary PdCuBP mesoporous nanospheres (MSs). It is demonstrated that PdCuBP MSs with three-dimensional dendritic mesopores disclose much better electrocatalytic performance toward ethanol oxidation electrocatalysis, due to more active sites, optimum electron/mass transfers, and better anti-poisoning ability.
