Abstract
The present invention has an object to provide an easy method for detecting a nucleic acid polymer in aqueous phase. The present invention provides a method for detecting the amount of nucleic acid polymer, which comprises the steps of modifying an intercalator to be amphiphilic by using a hydrophobic group, spreading the amphiphilic intercalator on an aqueous solution containing a nucleic acid polymer to form a monolayer of said nucleic acid polymer and said amphiphilic intercalator at the gas-water interface, and measuring surface pressures per unit area of said monolayer.
