E-skin is an integrated electronic system that can mimic the perceptual ability of human skin. Traditional analysis methods struggle to handle complex e-skin data, which include time series and multiple patterns, especially when dealing with intricate signals real-time responses. Recently, deep learning techniques, such as convolutional neural network, recurrent transformer methods, provide effective solutions automatically extract data features recognize significantly improving data. Deep not only capable handling multimodal but also response personalized predictions in dynamic environments. Nevertheless, problems insufficient annotation high demand for computational resources still limit application e-skin. Optimizing algorithms, efficiency, exploring hardware-algorithm co-designing will be key future development. This review aims present techniques applied inspiration subsequent researchers. We first summarize sources characteristics models applicable their applications analysis. Additionally, we discuss use e-skin, particularly health monitoring human-machine interactions, explore current challenges development directions.

Due to the rapid progression and aggressive metastasis of breast cancer, its diagnosis treatment remain a great challenge. The simultaneous inhibition tumor growth is necessary for cancer obtain ideal therapeutic outcomes. We herein report development radioactive hybrid semiconducting polymer nanoparticles (SPNH) imaging-guided tri-modal therapy cancer. Two polymers are used form SPNH with diameter around 60 nm via nano-coprecipitation they also labeled iodine-131 (131I) enhance imaging functions. formed show good radiolabeling stability excellent photodynamic photothermal effects under 808 laser irradiation produce singlet oxygen (1O2) heat. Moreover, can generate 1O2 ultrasound their sonodynamic properties. After intravenous tail vein injection, effectively accumulate in subcutaneous 4T1 tumors living mice as verified fluorescence single photon emission computed tomography (SPECT) imaging. With using an US, mediate (PDT), (PTT) (SDT) kill cells. Such leads improved efficacy inhibiting suppressing compared sole SDT combinational PDT-PTT. This study thus demonstrates applications diagnose combine different therapies effective treatment.

Direct electrochemical detection of miRNA biomarkers in tumor tissue interstitial fluid (TIF) holds great promise for adjuvant therapy tumors the perioperative period, yet is limited by background interference and weak signal. Herein, a wash-free separation-free biosensor based on photoexcited electro-driven reactive oxygen channeling analysis (LEOCA) developed to solve high-fidelity physiological samples. In presence miRNA, nanoacceptors (ultrasmall-size polydopamine, uPDA) are responsively assembled surface nanodonors (zirconium metal-organic framework, ZrMOF) form core-satellite aggregates. The produced lifetime-constraint singlet upon light irradiation captured catechol constrained uPDA, oxidized quinone immediately electro-reduced at transient collision process electrode, resulting cascade electron transfer amplified current. Thereby, nanosensor exhibits low limit (1.1 fM), high reproducibility (relative standard deviation 2.0%). Compared with quantitative real-time polymerase chain reaction (qRT-PCR), clinical accuracy (area under curve value) significantly increased from 0.75 0.93 distinguishing breast cancer patients healthy donors. This study demonstrates an inspiration synergy between nanodonor/nanoacceptor synchronous electrode bottleneck problem detecting unprocessed samples sample-in-answer-out manner.

Intestine damage is an acute abdominal disease that usually requires emergency sealing. However, traditional surgical suture not only causes secondary to the injured tissue, but also results in adhesion with other tissues cavity. To this end, a thermally reversible injectable gelatin-based hydrogel adhesive (GTPC) constructed by introducing transglutaminase (TGase) and proanthocyanidins (PCs) into gelatin system. By reducing catalytic activity of TGase, density covalent hydrogen bond crosslinking can be regulated tune sol-gel transition temperature hydrogels above physiological (42 °C) without any synthetic small molecules. The GTPC exhibits good tissue adhesion, antioxidant, antibacterial properties, which effectively seal damaged intestinal regulate microenvironment site, promoting repair regeneration. Intriguingly, temperature-induced disruption reformation confer asymmetric preventing when applied vivo. Animal experiment outcomes reveal firmly, accelerate healing, efficiently prevent postoperative adhesion.
