Special Issue Information

Dear colleagues,

Liquid biopsies provide a minimally invasive screening option for the analysis of tumor-specific material in biological fluids, such as the peripheral blood samples of patients. The analysis of circulating tumor cells or the tracking of tumor specific genetic or epigenetic alterations in cell-free circulating nucleic acids can provide real-time information, allowing for the detection of early-stage cancer, monitoring disease progression, predicting a response to drugs, and providing personalized treatment options. Thanks to recent technological advances, the field of liquid biopsies has now passed the proof-of-concept period and is beginning to find application in clinics. With the ability to manipulate fluids inside the architectures with dimensions that are comparable to the size of single cells, and with the ability to perform highly sensitive and quantitative analyses, microfluidic technologies have shown great potential for providing the tools needed for the handling of liquid biopsies.

With this Special Issue, we aim to tackle the recent, innovative microfluidics-based tools and the detection techniques for the handling and analysis of circulating tumor cells, exosomes, circulating tumor DNA, or circulating RNA, and we provide a detailed discussion regarding the potential opportunities for microfluidics-based approaches in cancer diagnostics.

Circulating tumor cells (CTCs) are important clinical markers for both cancer early diagnosis and prognosis. Various techniques have been developed in the past decade to isolate and quantify these cells from the blood while microfluidic technology attracts significant attention due to better controlled microenvironment. When combined with advanced nanotechnologies, CTC isolation performance in microfluidic devices can be further improved. In this article, by extending the wavy-herringbone concept developed earlier in our team, we prepared a hierarchical microfluidic chip by introducing a uniform coating of nanoparticles with anti-epithelial cell adhesion molecule (EpCAM) on wavy microgrooves. This hierarchical structured platform not only maintains the capture purity of the wavy-herringbone structure but improves the capture efficiency thanks to the larger surface area to volume ratio brought by nanoparticles. Our results demonstrated a capture efficiency of almost 100% at a low shear rate of 60/s. Even at a higher shear rate of 400/s, the hierarchical micro/nanostructures demonstrated an enhancement of up to ~3-fold for capture efficiency (i.e., 70%) and ~1.5-fold for capture purity (i.e., 68%), compared to wavy-herringbone structures without nanoparticle coating. With these promising results, this hierarchical structured platform represents a technological advancement for CTC isolation and cancer care. Full article
