Abstract: A method of detecting a biological sample includes the following steps. A magnetic sensor chip is provided, wherein the magnetic sensor chip includes a substrate and a magnetic sensing layer located on the substrate. Probes are connected to the magnetic sensor chip. A sample solution containing biological samples labeled with a first marker is provided on the magnetic sensor chip, so that the biological samples labeled with the first marker are hybridized with the probes. Magnetic beads labeled with a second marker are provided on the magnetic sensor chip, so that the magnetic beads labeled with the second marker are bound onto the biological samples labeled with the first marker. A signal sensed by the magnetic sensing layer is detected by a magnetic sensor.

Abstract: The disclosure provides a method for estimating a risk for a subject suffering from hepatocellular carcinoma, including: (a) determining methylation levels of APC gene, COX2 gene, RASSF1A gene and micro RNA-203 gene in a sample of a subject, respectively; (b) calculating a predicted score according to the methylation levels of the APC gene, COX2 gene, RASSF1A gene and micro RNA-203 gene; and (c) estimating a risk level for the subject suffering from hepatocellular carcinoma according to the predicted score.

Abstract: Methods for determining the likelihood of colorectal cancer (CRC) recurrence in a subject that involve measuring the expression level of two or more micro ribonucleic acids (miRNAs) in a biological sample comprising CRC tumor cells from said subject and using the normalized, measured expression levels to determine the likelihood of colorectal cancer recurrence for said subject. In the methods, the normalized expression levels of specific miRNAs are weighted by their contribution to CRC recurrence to calculate the likelihood of CRC recurrence. Kits for measuring the expression level of specific miRNAs that can be used in determining the likelihood of CRC recurrence are also provided.
