And these technologies were very promising, but the problem was that they were either inefficient, or they were difficult enough to use that most scientists had not adopted them for use in their own laboratories, or certainly for many clinical applications.
このような技術は有望視される一方で 効率が悪かったり 使い方がとても難しいという 問題がありました そのため 科学者の多くは 研究では採用することなく もちろん臨床に 応用されることも殆どありませんでした
