Highly Sensitive Virus Detection and
Analysis Equipment Using
Immunochromatographic Method

Highly-sensitive virus analysis equipment
developed by applying photographic silver
amplification technology

Silver amplification technology used in the photographic development is applied to the ultrahigh sensitive immunochromatography method, which expands the diameter of labeled particles by a hundredfold. This enables rapid and accurate detection of microbes such as influenza virus and mycoplasma bacteria, which are difficult to detect in the early stages when they are few in number.

Ultrahigh sensitive immunochromatography method

The technology enables rapid production of silver particles with a diameter of 10 μm through catalytic accumulation on gold colloid particles with a diameter of 50 nm that are used as labels. This expands the diameter of labeled particles by approximately a hundred times, thereby increasing their visibility.

Compact, Rapid Immunoanalyzer System
Using a Surface Plasmon-Enhanced
Fluorescence Method

Immunoanalyzer system for rapid measurement
developed through a practical application of
the SPF method

This immunoanalyzer system makes use of the antigen-antibody reaction in a practical application of the surface plasmon-enhanced fluorescence (SPF) method. Rapid detection was made possible by eliminating the washing function that reduced the required power of the light source and noise measurement required for measuring extremely low hormone levels inside the body.

SPF method

Only fluorescent particles near the Au film emit light, thereby eliminating the need for washing and other processes, reducing equipment size and shortening the time needed to obtain measurement results.
