چکیده

Integrating nanotechnology with established cancer research provides extraordinary opportunities to find essential breakthroughs in the fight against cancer. Nanowires and nanotubes are among the leading approaches under development for biological applications. Till now, the nanodevices face a key challenge to develop surfaces and structures that can be chemically modified for specific conjugation of proteins with limited non-specific adsorption. Here we demonstrate a microfluidic device with graphene oxide (GO) for selective and sensitive detection of circulating tumor cells aimed at early diagnosis of cancer. The functionalized GO can self-assembly on patterned gold surfaces via electrostatic interactions between functional groups on GO and gold surfaces.

Nanotechnology-Based Strategies for Early Cancer Diagnosis Using Circulating Tumor Cells as a Liquid Biopsy

Circulating tumor cells (CTCs) are cancer cells that shed from a primary tumor and circulate in the bloodstream. As a form of "tumor liquid biopsy", CTCs provide important information for the mechanistic investigation of cancer metastasis and the measurement of tumor genotype evolution during treatment and disease progression. However, the extremely low abundance of CTCs in the peripheral blood...

Aptamer-Conjugated Graphene Oxide Membranes for Highly Efficient Capture and Accurate Identification of Multiple Types of Circulating Tumor Cells

Tumor metastasis is responsible for 1 in 4 deaths in the United States. Though it has been well-documented over past two decades that circulating tumor cells (CTCs) in blood can be used as a biomarker for metastatic cancer, there are enormous challenges in capturing and identifying CTCs with sufficient sensitivity and specificity. Because of the heterogeneous expression of CTC markers, it is no...
