A method for identifying a biomolecule using a biomolecule detector having a field effect transistor (FET) is provided. The method comprises the steps of (a) heating a sample containing a biomolecule loaded in the detector to thereby elevate the temperature of the sample; (b) measuring electric current flowing through a channel formed between a source region and a drain region in the FET while raising the temperature in the step (a); (c) obtaining a transition temperature that is the temperature at maximum point of current variation from data measured in the step (b); and (d) identifying the biomolecule using the transition temperature obtained in the step (c).

Disclosed herein is a method of positively detecting toxic materials within a sample, the method including contacting sub-mitochondrial particles with an electron donor. The electron donor is reacted with an electron transfer system of the sub-mitochondrial particles to produce a reactant. A pH indicator has its pH adjusted to be in a range of 9 to 11. The pH indicator is added to each reactant. Color changes in the pH indicator permit the detection of toxins present in the sample.

Method for positively detecting toxic material

Provided is a method of amplifying nucleic acid from a comprising: contacting a cell-containing sample with a nonplanar solid substrate in a liquid medium having a pH range of 3.0-6.0 to attach the cell to the solid substrate; washing the nonplanar solid substrate to remove materials that are not attached thereto; and performing PCR using the nucleic acid from the cell attached to the nonplanar solid substrate as a template sample to amplify nucleic acid from the cell, wherein the contacting, washing and PCR processes are performed in a single vessel.
