Cancer genome analysis has recently attracted attention for personalized cancer treatment. In this treatment, evaluation of the ratio of cancer cells in a specimen tissue is essential for the precise analysis of the genome. Conventionally, the evaluation takes at least two days and depends on the skill of the pathologist. In our group, a terahertz chemical microscope (TCM) was developed to easily and quickly measure the number of cancer cells in a solution. In this study, an antibody was immobilized on a sensing plate using an avidin-biotin reaction to immobilize it for high density and to improve antibody alignment. In addition, as the detected terahertz signals vary depending on the sensitivity of the sensing plate, the sensitivity was evaluated using pH measurement. The result of the cancer cell detection was corrected using the result of pH measurement. These results indicate that a TCM is expected to be an excellent candidate for liquid biopsies in cancer diagnosis.

Cancer refers to any of countless infections characterized by the development of abnormal cells that divide uncontrollably and can invade and destroy normal body tissue. Malignant growth frequently can spread all through your body. Cancer is the second driving reason for death on the planet. In this paper, we propose to found a H-cell to screen carcinogenic cells in a given sample of blood based on the principle of diffusion. This model incorporates the planning of a MEMS-based microfluidic channel to screen and recognize different cells depending on the size and various characteristics of the cells. Some of the methods which are implemented not efficient models for cancer cells detection in blood. The mass, displacement technique has been implemented in this investigation for cancer cell detection, with the help of this achieves the accuracy and better throughput. One cancer cell contains = 1.70371e-24 mass, such that with a weight of this formula, find out the total no of cells in the blood. This is the best method compared to existed methods. Using this count, the weight has been calculate early-stage cancer and treatment with a simple manner, CTCs in the blood is the un potential matter for health, H-cells have been measured with proposed weight and force technique such that in this investigation also calculate the healthy and cancer cells also. Finally, using this methodology achieves 93.58% accuracy, 0.00124 MSE. These are very good results compared to conventional methods.

Since cancer becomes the most deadly disease to our health, research on early detection on cancer cells is necessary for clinical treatment. The combination of microfluidic device with cell biology has shown a unique method for cancer cell research. In the present review, recent development on microfluidic chip for cancer cell detection and diagnosis will be addressed. Some typical microfluidic chips focussed on cancer cells and their advantages for different kinds of cancer cell detection and diagnosis will be listed, and the cell capture methods within the microfluidics will be simultaneously mentioned. Then the potential direction of microfluidic chip on cancer cell detection and diagnosis in the future is also discussed.

Since the crucial role of the microenvironment has been highlighted, many studies have been focused on the role of biomechanics in cancer cell growth and the invasion of the surrounding environment. Despite the search in recent years for molecular biomarkers to try to classify and stratify cancers, much effort needs to be made to take account of morphological and nanomechanical parameters that could provide supplementary information concerning tissue complexity adaptation during cancer development. The biomechanical properties of cancer cells and their surrounding extracellular matrix have actually been proposed as promising biomarkers for cancer diagnosis and prognosis. The present review first describes the main methods used to study the mechanical properties of cancer cells. Then, we address the nanomechanical description of cultured cancer cells and the crucial role of the cytoskeleton for biomechanics linked with cell morphology. Finally, we depict how studying interaction of tumor cells with their surrounding microenvironment is crucial to integrating biomechanical properties in our understanding of tumor growth and local invasion.
