Introduction

Microfluidic organ-on-a-chip technology represents a significant advancement, covering critical areas like drug screening, disease modeling, and personalized medicine. These devices are engineered to mimic physiological environments, offering benefits for research, though challenges persist in their broader adoption[1].

Microfluidic platforms are also central to point-of-care diagnostics. They enable rapid, accurate, and cost-effective disease detection outside traditional labs. This capacity holds substantial promise for global health, particularly in resource-limited regions, leveraging various fabrication and detection strategies[2].

The progress in droplet microfluidics highlights its utility in biological applications, including single-cell analysis, high-throughput screening, and digital Polymerase Chain Reaction. The precise volume control and compartmentalization offered by droplets are crucial for enhancing assay sensitivity and reducing reagent consumption[3].

Microfluidic cell culture systems are revolutionizing drug discovery and development. They provide more physiologically relevant models compared to traditional two-dimensional cultures. These systems excel at mimicking complex tissue microenvironments, which facilitates better predictions of drug efficacy and toxicity in a high-throughput manner[4].

Advances in microfluidic technology are significantly impacting cancer diagnostics. This includes capabilities like circulating tumor cell isolation, exosome analysis, and liquid biopsy. These chips enable early detection, personalized treatment monitoring, and fundamental cancer research through precise sample manipulation and high sensitivity[5].

Paper-based microfluidic analytical devices (μPADs) show considerable progress for point-of-care testing. Their low cost, portability, and ease of use make them highly suitable for rapid diagnostics in resource-limited settings. Various detection mechanisms and fabrication techniques are continually being refined, promising further advancements[6].

Microfluidic platforms are vital for advancing single-cell analysis, encompassing everything from isolating individual cells to conducting multi-omics investigations. These chips provide precise control over cellular environments, enabling detailed studies of cellular heterogeneity and dynamic processes relevant to disease mechanisms and therapeutic responses[7].

Recent progress in microfluidic devices extends to preparing various drug delivery systems, such as nanoparticles, liposomes, and microgels. This technology allows for precise control over particle size, morphology, and encapsulation efficiency, leading to more uniform and effective therapeutic agents with enhanced pharmacokinetic profiles[8].

Microfluidics serves as a foundational technology across numerous biomedical applications, including diagnostics, therapeutics, and fundamental biological research. The precise control over fluids at the microscale empowers new discoveries and practical solutions in areas like cell manipulation, drug screening, and point-of-care devices[9].

The evolution of microfluidic immunoassays is also noteworthy, demonstrating a shift from complex lab-based systems to user-friendly point-of-care diagnostic tools. Innovative chip designs and detection principles have enhanced sensitivity, specificity, and throughput, making these assays suitable for diverse clinical and environmental monitoring applications[10].

Description

Microfluidics is fundamentally changing biomedical research and clinical practice by enabling precise control over fluids at the microscale. This technology serves as an essential tool for creating advanced biological models. For example, microfluidic organ-on-a-chip technology is highly effective for drug screening, disease modeling, and developing personalized medicine approaches. These systems excel at mimicking complex physiological environments, offering a more relevant testing ground than traditional methods, though challenges in widespread adoption remain [1]. Concurrently, microfluidic cell culture systems are transforming drug discovery by providing models that accurately reflect complex tissue microenvironments. This capability significantly improves predictions of drug efficacy and toxicity, facilitating high-throughput analysis in the development process [4].

In diagnostics, microfluidics offers significant advantages, particularly for point-of-care applications. Microfluidic platforms are designed to provide rapid, accurate, and cost-effective disease detection outside conventional laboratory settings [2]. This is especially critical for global health initiatives and in resource-limited areas, where access to sophisticated lab equipment is scarce. A notable subset of this technology is paper-based microfluidic analytical devices (μPADs). These devices are celebrated for their low cost, portability, and ease of use, making them ideal for quick diagnostics in the field. Various detection mechanisms and fabrication techniques have been developed to enhance their utility and future prospects [6]. The evolution of microfluidic immunoassays also highlights this trend, moving from intricate lab-based systems to user-friendly point-of-care tools with enhanced sensitivity and specificity [10].

The precision offered by microfluidics is particularly impactful in single-cell analysis. Microfluidic platforms are key for advancing studies from isolating individual cells to conducting multi-omics investigations [7]. These chips offer exact control over cellular environments, allowing for detailed examination of cellular heterogeneity and dynamic processes. This provides crucial insights into disease mechanisms and therapeutic responses. Similarly, droplet microfluidics has seen substantial progress, focusing on biological applications such as single-cell analysis, high-throughput screening, and digital Polymerase Chain Reaction. The precise volume control and compartmentalization provided by droplets are vital for increasing assay sensitivity and reducing reagent consumption, making experiments more efficient and revealing [3].

Microfluidic technology also presents significant advancements in cancer diagnostics. It includes methods for circulating tumor cell isolation, detailed exosome analysis, and liquid biopsy. These capabilities are crucial for early detection, monitoring personalized treatments, and supporting fundamental cancer research by enabling precise sample manipulation and high sensitivity [5]. Furthermore, microfluidic devices are making notable contributions to the preparation of drug delivery systems. They are used to create nanoparticles, liposomes, and microgels, allowing for precise control over particle size, morphology, and encapsulation efficiency. This leads to the development of more uniform and effective therapeutic agents with improved pharmacokinetic profiles, ultimately enhancing treatment outcomes [8].

Overall, microfluidics serves as an enabling technology that underpins diverse biomedical applications, from diagnostics and therapeutics to fundamental biological investigations [9]. The capacity for precise control over microscale fluids empowers new discoveries and practical solutions across many fields. This includes intricate cell manipulation, efficient drug screening, and the development of essential point-of-care devices. The continuous progress in this field promises further innovations that will continue to revolutionize healthcare and scientific understanding.
