    摘要: Provided is an apparatus for detecting bio materials and a method for detecting bio materials by using the apparatus. The apparatus includes a bio material reacting unit, an optical source unit, and a detecting unit. The bio material reacting unit includes bio sensing materials immobilized on gold nanoparticles. The optical source unit emits light toward the bio material reacting unit. The detecting unit measures variations of surface absorbance of the gold nanoparticles by detecting light transmitted through the bio material reacting unit before and after a bio material is bound to the bio sensing materials.

    摘要: Provided are a method and apparatus for measuring an isoelectric point using a field effect transistor. The method includes providing a field effect transistor including a substrate, source and drain electrodes disposed on the substrate and spaced apart from each other, and a channel region between the source and drain electrodes, providing a first electrolyte solution having a first concentration to the channel region of the field effect transistor and measuring a first current value of the channel region between the source and drain electrodes, providing a second electrolyte solution having a second concentration greater than the first concentration and measuring a second current value of the channel region between the source and drain electrodes, and determining the isoelectric point of the field effect transistor or a material disposed on the field effect transistor using a difference between the first and second current values.
