Title: Masafumi Toyama: Innovator in Microprotein Inactivation and Nucleic Acid Amplification

Introduction

Masafumi Toyama is a notable inventor based in Yokohama, Japan. He has made significant contributions to the fields of microprotein inactivation and nucleic acid amplification. With a total of 2 patents, Toyama's work showcases innovative approaches to complex scientific challenges.

Latest Patents

Toyama's latest patents include the development of microprotein-inactivating ultrafine metal particles. These particles comprise ultrafine metal particles that have a bond between an organic acid component and a metal. They exhibit an infrared absorption peak ascribable to the bond between the organic acid and the metal near 1518 cm. This technology is capable of efficiently inactivating microproteins without impairing the properties of the resin or its formability. When utilized in a resin composition or as a coating agent, these particles effectively inactivate microproteins.

Another significant patent is a nucleic acid amplification method based on a new principle. This method allows for the amplification of a nucleic acid with a specific nucleotide sequence in a simple, efficient manner and within a short time frame. The process involves conducting a DNA polymerase chain reaction using a template DNA that includes the nucleotide sequence to be amplified. It also employs a primer pair that is complementary to the target sequence, producing a linear DNA fragment. Subsequently, a chain-substituting DNA polymerase chain reaction is conducted using cyclic single-stranded DNA as a template.
