| 研究実績の概要 |
We demonstrated a novel on-chip biosensor, which is composed of a silicon nanodisk array that tailors a chiral field to significantly increase the interaction between the excitation light and chiral molecules via exploiting a dark mode. Specifically, we used the array with pairs of chemical and biological enantiomers to show >100x enhanced chiral light-molecule interaction with negligible artifacts for ROA measurements.

理由
We demonstrated a novel on-chip chiral biosensor based on superchiral-field-enhanced Raman optical activity as we initially planned.
|
| 今後の研究の推進方策 |
Based on the on-chip chiral biosensor based on Raman optical activity we developed in this fiscal year, we will further explore its practical applications in various research fields.
|
| 次年度使用額が生じた理由 |
Due to the COVID-19, some article costs and travel expenses could not be used as my previous plan. I will rearrange and use this incurring
amount in the next fiscal year to help further accelerate the progress of this research project.
