Sepsis remains a leading cause of global mortality, largely due to the difficulty of achieving a timely diagnosis. The conventional diagnostic approaches for sepsis often face limitations in speed, portability, sensitivity, and specificity, which can lead to delayed or missed diagnoses. In response, microfluidic devices have emerged as powerful tools for point-of-care precise sample handling and preparation, enabling efficient isolation and detection of sepsis-causing bacteria and biomarkers. Fabrication techniques of these microfluidic devices, ranging from photolithography to xurography, have significantly advanced and paved the way for complex designs and improved functionality. Microfluidic platforms offer various benefits in sepsis diagnosis and prognosis. They facilitate rapid and automated sample processing, enhancing turnaround times and reducing the risk of contamination. Moreover, the integration of microfluidic systems with advanced detection methods enables the simultaneous analysis of multiple biomarkers, thereby enhancing diagnostic accuracy and prognostic capabilities.

This work investigated the memory capabilities of zebrafish larvae across different developmental stages (5-9 days post-fertilization) by employing sound stimuli within the microfluidic environment. Notably, the sound signal with 1200 Hz frequency was observed to be significantly sensitive among all the considered developmental stages in stimulating the responses. In addition, the impact of the memory enhancer drug methylene blue (MB) was tested, revealing a significant enhancement in cognitive performance compared to controls. Specifically, learning (training) and memory (post-training) were observed to exhibit 2-fold and 20-fold increases, respectively, in MB-exposed larvae. In addition to sound stimuli and memory enhancer drugs, the impact of environmental complexity on cognitive abilities was examined by employing different designs of microchannels, such as series, parallel, and combined configurations.

The electric field induces complex electrohydrodynamic behaviors in such systems with considerable impact on their deformation, motion, and interaction with the surrounding fluid. Introducing an electric field exerts stresses at the interface of these fluids, which ensures precise control over their deformation and motion with the features of droplets or vesicles that are vital for their subsequent manipulation inside confined microchannels. Here, electrically modulated transport dynamics in soft multiphase systems, specifically droplets and vesicles, in microfluidic systems are studied meticulously. In this review work, we study how the electric field strength, fluid properties, and membrane characteristics, all of which are important to the directed motion of these systems, are coupled to one another. It also notes that vesicles, with their bilayer lipid membranes, have unique dynamics-such as the formation of membrane tensions and bending rigidity-that affect their electrohydrodynamic behaviors, unlike simple droplets. Studying the electrically driven dynamics of the soft matter, this review offers useful perspectives on the creation of next-generation microfluidics devices, ranging from drug delivery to synthetic biology and materials manufacturing. The effects of the field strength, frequency, and geometry on the transport properties of the droplets and vesicles and highlighting the rich interplay between the electrostatic forces and the inherent properties of soft matter are studied systematically. Recent advances in experimental methods (such as high-precision imaging, micro-manipulation, and sophisticated computational modeling) have also taken our understanding of these electrohydrodynamic processes to new heights. This review further explores potential applications of these technologies in lab-on-a-chip platforms, drug delivery systems, and bioanalytical tools and highlights challenges, including stability, scalability, and reproducibility. The conclusion includes proposed directions for future research aimed at enhancing the localization, control, and efficiency of electrokinetic manipulation in soft matter-based microfluidic systems.</p>","PeriodicalId":8855,"journal":{"name":"Biomicrofluidics","volume":"19 3","pages":"031503"},"PeriodicalIF":2.6,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12140804/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144246235","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, their rapid deployment has exposed them to diverse security threats, including structural tampering, material degradation, sample-level interference, and intellectual property (IP) theft, such as counterfeiting, overbuilding, and piracy. This perspective highlights emerging attack vectors and countermeasures aimed at mitigating these risks. Structural attacks, such as stealthy design code modifications, can result in faulty diagnostics. To address this, deep learning -based anomaly detection leverages microstructural changes, including optical changes such as shadows or reflections, to identify and resolve faults. Material-level countermeasures, including mechano-responsive dyes and spectrometric watermarking, safeguard against subtle chemical alterations during fabrication. Sample-level protections, such as molecular barcoding, ensure bio-sample integrity by embedding unique DNA sequences for authentication. At the IP level, techniques like watermarking, physically unclonable functions, fingerprinting, and obfuscation schemes provide robust defenses against reverse engineering and counterfeiting.
