Abstract

The influences of Methotrexate as fluorophor, scatterer, absorber in turbid material by light scattering were interpreted for the scattered fluorescence intensity and wavelength, it has been studied the molecular properties by laser induced fluorescence spectroscopy. It has been found that the effects of optical properties in scattering media by the optical parameters((${\mu}_s$, ${\mu}_a$, ${\mu}_t$). The value of scattering coefficient ${\mu}_s$ is large by means of the increasing particles of L-${\alpha}$-Phosphatidylcholine, it has been found that the slope decays exponentially as a function of depth from laser source to detector. It may also aid in designing the best model for oil chemistry, laser medicine and application of medical engineering.

Methotrexate의 영향은 혼탁매질에서 형광체, 산란체와 응흡수체에 의해 파장과 산란된 형광 세기로 규명되는데, laser induced fluorescence(LIF) 분광학에 의해 분자특성으로 나타난다. 산란매질에서 광학적 효과는 광학적 파라미터들((${\mu}_s$, ${\mu}_a$, ${\mu}_t$)에 의해 표현되고 응집은 고-액상 분리공정에서 중요하게 활용되고 있다. 따라서 입자가 서로 접근될 때 콜로이드 입자들의 상호작용을 LIF와 응집효과로 분석하였다. 산란계수는 산란매질, L-${\alpha}$-Phosphatidylcholine의 농도가 증가함에 따라 산란 광학적 파라미터가 증가하였으나 흡수 파라미터는 감소하였다. 광학적 파라미터들은 레이저 광원에서 검출기까지 깊이의 함수에 의해 깊이가 깊어짐에 따라 산란세기가 기하급수적으로 감소함을 알 수 있다. 이는 유지화학, 생의학 생성물, 레이저 의학, 의공학 분야적용에 LIF와 입자이동 현상은 아주 적합한 모델 연구에 큰 도움이 될 것이다.
