AI Technical Summary

Technical Problem

Existing methods for producing odor sensors using lipid bilayer membranes with sensor proteins are inefficient, and there is a need for improved production efficiency of insect cells that function as chemical sensors for mass production of odor sensors.

Method used

A method for expanding insect cell culture by subculturing at a confluency higher than 50%, with specific cell concentration and culture period conditions, including the use of exogenous polynucleotides for sensor proteins, to enhance cell expansion and sensor protein activity.

Benefits of technology

The method significantly enhances the efficiency of insect cell expansion, allowing for higher cell proliferation rates and increased sensor protein activity, facilitating mass production of chemical sensors.
