Among various technological routes, electrochemically directed synthesis offers exceptional synthesis-site density thanks to its compatibility with semiconductor microfabrication processes. Yet increasing density typically comes at the expense of reduced per-site oligonucleotide yield, compromising the practical utility of these synthesis platforms for reliable data recovery. Here we report a porous silica thin-film strategy in order to address this fundamental trade-off by substantially increasing the effective on-chip synthesis surface area while preserving spatial confinement during electrochemically generated acid-mediated deblocking. The porous thin-film, fabricated via a sacrificial templating approach, forms an interconnected high-surface-area porous network that enables efficient reagent transport and stable electrochemical control. The presented method enables an areal oligonucleotide yield of more than 1821 pmol/cm², which represents more than 11-fold enhancement compared to a planar silica substrate. Moreover, this platform achieves comparable error statistics of deletion, insertion and substitution compared to other laboratory-built DNA data writing systems. Using this platform, we demonstrated parallel synthesis of 121-nt oligonucleotides and successful encoding, writing and error-corrected recovery of digital information. These results establish a scalable strategy for high-yield on-chip DNA synthesis and provide a practical pathway towards integrated molecular data storage systems.</p>","PeriodicalId":18560,"journal":{"name":"Microsystems & Nanoengineering","volume":"12 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2026-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13658797/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149168271","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This condition leads to premature muscle fatigue and a decline in muscle function, highlighting the necessity for highly sensitive diagnostic methods to detect impairment prior to the occurrence of structural damage. Conventional diagnostic methods, including electromyography, serum biomarker assays, and medical imaging, often fail to detect early and subtle alterations in myotube electrophysiological responsiveness because of limited temporal accuracy and insufficient target specificity. Furthermore, these techniques are limited in resolving dynamic electrophysiological fluctuations as well as characterizing the coupling between electrical signaling and intracellular calcium dynamics. Herein, we have developed an integrated bimodal biosensing platform that combines microelectrode array (MEA)-based electrophysiological recording with high-resolution, fluorescence-based calcium imaging. This platform performs coordinated and real-time tracking of extracellular field potentials and intracellular calcium transients across networks of differentiated C2C12 myotubes. Using an in vitro model of LPS-induced inflammatory skeletal muscle atrophy, LPS exposure progressively disrupted spontaneous electrical firing, field potential amplitude, and intracellular calcium transients in a concentration- and time-dependent manner. Diclofenac, a clinically applied anti-inflammatory agent, effectively maintained both electrophysiological function and calcium homeostasis in myotubes under inflammatory stress. Therefore, our bimodal platform functions as a robust, real-time preclinical tool for the detection of incipient inflammatory myopathy.

However, existing flexible sensors are often limited by narrow operating temperature ranges, thermally induced signal interference, and insufficient durability under cyclic mechanical loading. This study develops a flexible wide-temperature-range temperature-pressure sensor based on polyacrylonitrile fiber mats. By combining laser processing or heat treatment, the electrical properties of polyacrylonitrile are regulated in situ, enabling its use as a multimodal sensing material. Temperature sensing is achieved through the thermosensitive effect of the treated polyacrylonitrile fiber mat, with a resolution of 0.1 °C in the temperature range of 25 °C-300 °C. Pressure sensing is realized through the piezoresistive response of polyacrylonitrile nanowires, featuring a measurement range of 0-480 kPa and response/recovery time of 53.2 ms/8.8 ms. After 10,000 loading-unloading cycles, the pressure-response attenuation remains below 1%, demonstrating good mechanical durability. Furthermore, the sensor exhibits reliable responses under dynamic thermal-mechanical coupling conditions and can be integrated with robotic grippers for simultaneous temperature and pressure perception. These results suggest that the proposed sensor holds promise for lithium-ion battery thermal management, industrial equipment condition monitoring, and emergency rescue applications in high-temperature environments.</p>","PeriodicalId":18560,"journal":{"name":"Microsystems & Nanoengineering","volume":"12 1","pages":""},"PeriodicalIF":11.1,"publicationDate":"2026-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13620146/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149075194","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
