Raman microspectroscopy is a promising tool for microbial analysis at single cell level since it can rapidly measure the cell materials including lipids, nucleic acids, and proteins by measuring the inelastic scattering of a molecule irradiated by monochromatic lights. Using Raman spectra provides h...

라만 분광법의 특징은? | 라만 분광법은 레이저가 분자의 공명에 의해 산란되는 특성을 이용하여 세포 내 지질, 핵산, 단백질 등의 구성물질을 신속하게 측정할 수 있어 단세포 수준의 세균 검측에 적합한 기술로 알려져 있다. 세포 구성물질에 대한 높은 특이성과 민감성 때문에 라만 스펙트라(spectra)만으로 일부 종 수준의 세균 계통분석이 가능하다. | |
세균은 어떠한 환경에서 군집을 이루는가? | 세균은 대기, 토양, 물 뿐만 아니라 식물과 동물을 포함한 거의 모든 환경에 군집(community)을 이루며 살아가며, 군집은 그 구조와 다양성에 따라 서로 다른 기능으로 나타나게 된다. 군집을 이루는 기본 단위는 세균 한 종(species)이며, 연구자들은 관심 있는 종을 분리 및 배양 연구를 통해 환경의 기능을 추론한다. | |
라만 분광법이 세균 계통분석에 사용될 수 있는 이유는? | 라만 분광법은 레이저가 분자의 공명에 의해 산란되는 특성을 이용하여 세포 내 지질, 핵산, 단백질 등의 구성물질을 신속하게 측정할 수 있어 단세포 수준의 세균 검측에 적합한 기술로 알려져 있다. 세포 구성물질에 대한 높은 특이성과 민감성 때문에 라만 스펙트라(spectra)만으로 일부 종 수준의 세균 계통분석이 가능하다. 또한 탄소-13, 수소-2 등의 동위원소를 동시에 사용하였을 경우 단세포의 생리적 활성 변화에 대한 정량평가에 활용 할 수 있다. |
