Resonance Raman spectroscopy measurements of lysozyme-bound single-walled carbon nanotubes have been made during different stages of the chemically and thermally induced misfolding and of the denaturation process of nanotube-bound lysozymes. Changes to the Raman intensity of single-walled carbon nanotubes (SWNTs) have been observed during the denaturation of lysozyme. The Raman intensity changes are attributed to excitonic transition energy ( ) shifts of the SWNTs during the denaturation of lysozyme. The shift of SWNTs was confirmed by photoluminescence measurements.
在化学和热诱导的溶菌酶错误折叠的不同阶段以及与纳米管结合的溶菌酶的变性过程中,对与溶菌酶结合的单壁碳纳米管进行了共振拉曼光谱测量。在溶菌酶变性过程中观察到了单壁碳纳米管(SWNTs)拉曼强度的变化。拉曼强度的变化归因于溶菌酶变性过程中SWNTs的激子跃迁能量()的变化。SWNTs的变化通过光致发光测量得到了证实。
