Advances in Microfluidic and Nanotechnology-Based Approaches for Cancer Diagnosis, Drug Delivery, and Therapy

About this Research Topic

Background

The integration of microfluidics and nanotechnology has revolutionized the landscape of cancer research, offering unprecedented precision in both diagnostics and therapeutics. Microfluidic technologies allow manipulation of fluids at the microscale, providing platforms for real-time monitoring, high-throughput screening, and single-cell analysis. These systems are especially powerful for modeling tumor microenvironments, isolating circulating tumor cells, and enabling minimally invasive diagnostic solutions.

Concurrently, advances in nanotechnology, particularly in the development of colloidal nanomaterials such as nanoparticles, nanocarriers, and nanosensors, have led to breakthroughs in targeted drug delivery and tumor-specific imaging. Colloidal systems offer tunable surface chemistry, controlled size and shape, and multifunctionality, making them ideal for overcoming biological barriers and achieving site-specific therapeutic action with minimal off-target effects.

This Research Topic seeks to highlight the convergence of microfluidic engineering and colloidal nanotechnology in tackling critical challenges in oncology. Conventional diagnostic and treatment modalities often lack sensitivity, selectivity, and personalization. In contrast, microfluidic-nanotechnology platforms hold the potential to transform cancer care by enabling patient-specific approaches, integrating biosensing and therapeutic functionalities, and improving clinical outcomes through data-driven and material-focused innovation.

We particularly welcome contributions that demonstrate how colloidal materials such as polymeric nanoparticles, lipid-based carriers, metallic nanostructures, and hybrid systems—can be integrated into microfluidic platforms to enhance diagnostic resolution, therapeutic precision, and biological compatibility. Submissions may include original research, reviews, or perspective articles that bridge the gap between materials science, bioengineering, and clinical oncology.

Scope of interest includes, but is not limited to:

-Development and application of tumor-on-a-chip and organ-on-a-chip systems

-Colloidal nanocarriers for targeted and stimuli-responsive drug delivery

-Microfluidic platforms for personalized drug screening and cancer diagnostics

-Biosensors and nanosensors for early detection of cancer biomarkers

-Smart colloidal systems responsive to pH, temperature, or enzymatic cues

-Integration of artificial intelligence and machine learning with nano-micro systems

-Hybrid platforms combining nanomaterials and microfluidics for theranostics

By showcasing interdisciplinary research at the interface of microfluidics, colloidal materials, and nanomedicine, this Topic aims to advance the development of next-generation cancer technologies with real clinical impact.

Frequently asked questions

• What is a Research Topic?

  Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

  Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

• Why does Frontiers publish Research Topics? 

  The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

  Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

• Why are Research Topics important for journals?

  As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

  A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

• How do we ensure the quality of articles within Research Topics?

  Each Research Topic must be approved by the specialty chief editor, and it falls under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

  In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

• What are the benefits of publishing my article in a Research Topic?

  Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

  As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

  Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.

   
• What types of articles can be published in a Research Topic?
