Special Issue Information

Dear Colleagues,

Advances in microfluidics and organoids have revolutionized biomedicine by providing biomimetic models that overcome the limitations of traditional cell cultures and animal models. These technologies enable the precise control of microenvironments, cellular interactions, and dynamic physiological conditions, fostering breakthroughs in tissue engineering, pharmacology, toxicology, and regenerative medicine.

Microfluidics allows for controlled fluid dynamics, gradient formation, and real-time cellular monitoring, making it a key tool for studying biological barriers, drug delivery, and disease modeling. Meanwhile, organoids, derived from stem cells, offer 3D tissue architectures that better recapitulate developmental processes, disease progression, and therapeutic responses.

These platforms also play a crucial role in nanomedicine, supporting the development of nanoparticle-based therapies, biosensors, and advanced preclinical models.

This Special Issue welcomes original research, reviews, and perspectives on microfluidics and organoids, including the following:

  • Development of microfluidic devices for tissue modeling, drug screening, and physiological microenvironment simulation;
  • Innovations in organoid bioengineering, including enhanced tissue maturation, vascularization, and phenotypic stability;
  • Microfluidic platforms for toxicity testing and safety assessment of new compounds;
  • Advanced cell culture and differentiation strategies for creating more complex and functional organoids;
  • Integration of biosensors and live imaging techniques for real-time monitoring of organoids and microfluidic systems;
  • Computational modeling and artificial intelligence applied to the optimization of microfluidic and organoid systems;
  • Applications in nanomedicine, including nanoparticle-based therapies, nanobiosensor development, and toxicity testing in biomimetic platforms.

We invite contributions that explore how these technologies are shaping the future of biomedicine, the pharmaceutical industry, and translational research.

Cell migration plays a central role in physiological processes such as wound healing, tissue regeneration, and immune responses, as well as in pathological conditions like chronic inflammation and tumor metastasis. Among the in vitro approaches to study this phenomenon, the conventional wound healing assay (scratch assay) has been widely used due to its simplicity and low cost. However, its limitations, including poor reproducibility, damage to the extracellular matrix (ECM), and lack of dynamic physiological conditions, have prompted the development of microfluidic alternatives. Scratch-on-a-chip platforms integrate engineering and microtechnology to provide standardized, non-destructive methods for wound generation, preserve ECM integrity, and allow precise control of the cellular microenvironment. These systems also enable miniaturization, reducing reagent and cell consumption, while facilitating the application of biochemical or physical stimuli and real-time monitoring. This review synthesizes advances reported in the literature, addressing the different wound induction strategies (enzymatic depletion, physical depletion, and physical exclusion), the role of ECM composition, and the impact of mechanical forces such as shear stress. Overall, scratch-on-a-chip assays emerge as promising tools that enhance reproducibility, better mimic in vivo conditions, and broaden applications for therapeutic testing and mechanistic studies in cell migration.
