2022 Fiscal Year Research-status Report

感染症拡大抑制に資する低温プラズマ及びプラズマ活性溶液の開発

Research Project

Project/Area Number 21K18616
Research InstitutionNagoya University

Principal Investigator

田中 宏昌  名古屋大学, 低温プラズマ科学研究センター, 教授 (00508129)

Project Period (FY) 2021-07-09 – 2024-03-31
Keywordsプラズマ活性溶液
Outline of Annual Research Achievements

一昨年度、ベルリサーチセンター小屋博士と共同で、BSL2で取り扱いが可能なヒトコロナウイルスOC43の実験系を立ち上げたり、受託解析によMild PALの豚コロナウイルス(PVDE)に対する不活化能と新型コロナウイルスSARS-Cov2デルタ株に対する不活化能を調べ、コロナウイルスを不活化するPALの条件を見出したが、昨年度は、更に、ペンタイプのプラズマ装置の実験系を立ち上げたり、PALの成分に関する知見を深めるための基礎的な実験を進めた。ペンタイプのプラズマ装置を使い、照射時間や照射距離を変えながらPALを作製し、pHや過酸化水素濃度、亜硝酸イオン濃度を計測し、どのようなパラメーターセットでどのような条件のPALが作製できるかの基礎的なデータを収集した。また、PALの成分解析の一環として、ESR、NMR、GC-MS、LC-MSを駆使して、これまでにPALの成分として同定されたピルビン酸、酢酸、ギ酸、グリオキシル酸、2,3-ジメチル酒石酸の反応生成メカニズムを明らかにし、Plasma Processes and Polymersに論文公表した。更に、完全密閉プラズマ活性溶液作製装置を用い、アルゴン雰囲気下で、フィードガスとしてアルゴンガス100%、アルゴンガス90%+酸素ガス10%、アルゴンガス90%+窒素ガス10%、アルゴンガス80%+酸素ガス10%+窒素ガス10%の酸素の条件下でPALを作製し、pHや過酸化水素濃度、亜硝酸イオン濃度を計測し、成分がどのように変化するのかの解析を進めた。

Current Status of Research Progress
Current Status of Research Progress

2: Research has progressed on the whole more than it was originally planned.

Reason

BSL2で取り扱い可能なヒトコロナウイルスOC43の実験系が一昨年度立ち上げられ、昨年度はPALの成分やその反応機構に関する研究が躍進したため、コロナ不活化のためのPALの開発に向けて大きく前進し、おおむね順調に進展していると言える。

Strategy for Future Research Activity

昨年度、PALの成分に関する知見が更に蓄積されたが、亜硝酸イオン濃度が高いことがコロナウイルスの不活化能上昇と関係しているかどうかを調べるために、引き続き、完全閉鎖型のプラズマ活性溶液作製装置を用い、アルゴン雰囲気化でプラズマ活性溶液を作製し、窒素ガス添加によるPALのコロナウイルス不活化能の違いを調べたり、また、アルゴン雰囲気化で、窒素ガスや酸素ガスを 様々な混合比で添加することにより、コロナウイルス不活化能におけるPALの最適化を試みる。また最終年度であるため、これらの成果をまとめて論文を投稿したいと考えている。
