A reduction chemistry-based, molecular dynamics simulation-assisted nanopore method was developed for the simultaneous determination of IgG and IgM without any concerns of undesirable effects to blood.

The small current detection circuit is the core component of the accurate detection of the nanopore sensor. In this paper, a compact, low-noise, and high-speed trans-impedance amplifier is built for the nanopore detection system. The amplifier consists of two amplification stages. The first stage performs low-noise trans-impedance amplification by using ADA4530-1, which is a high-performance FET operational amplifier, and a high-ohm feedback resistor of 1 GΩ. The high pass shelf filter in the second stage recovers the higher frequency above the 3 dB cutoff in the first stage to extend the maximum bandwidth up to 50 kHz. The amplifier shows a low noise below sub-2 pA rms when tuned to have a bandwidth of around 5 kHz. It also guarantees a stable frequency response in the nanopore sensor.

We developed a perovskite solar cell based on GO/PEDOT:PSS bimolecular layer as hole transfer material.The hole transmission layer can effectively improve the device filling factor and reduce leakage current through effective extraction of holes and effective shielding of electrons.Eventually we increased the device efficiency from 11.4% to 14.1%.

Humans could sensitively perceive and identify objects through dense mechanoreceptors distributed on the skin of curved fingertips. Inspired by this biological structure, this study presents a general conformal integration method for flexible tactile sensors on curved fingertip surfaces. By adopting a spherical partition design and an inverse mode auxiliary layering process, it ensures the uniform distribution of stress at different curvatures. The sensor adopts a 3 × 3 tactile array configuration, replicating the 3D curved surface distribution of human mechanoreceptors. By analyzing multi-point outputs, the sensor reconstructs contact pressure gradients and infers the softness or stiffness of touched objects, thereby realizing both structural and functional bionics. These sensors exhibit excellent linearity within 0–100 kPa (sensitivity ≈ 36.86 kPa⁻¹), fast response (2 ms), and outstanding durability (signal decay of only 1.94% after 30,000 cycles). It is worth noting that this conformal tactile fingertip integration method not only exhibits uniform responses at each unit, but also has the preload-free advantage, and then performs well in pulse detection and hardness discrimination. This work provides a novel bioinspired pathway for conformal integration of tactile sensors, enabling artificial skins and robotic fingertips with human-like tactile perception.

This article provides a low cost and green environmental preparation method to produce a high performance of stannum‐carbon lithium battery anode material. The advantage of this method is not only for improving the performance and stability comparing with the stannum‐carbon lithium battery, but also show a way for the industrial scale for the applications at the same time. This paper provides a reasonably designed hybrid composite as lithium ion battery anode that shows a reversible capacity of 440 mAh g ⁻¹ after 500 cycles at 1.0 A g ⁻¹ . This result is mainly attributed to the nanocrystallization of stannum and the introduction of expansion space by combination of wheat flour nature properties and redox process.
