Abstract	본 논문에서는 구조가 간단하고 생체분야에 응용 가능한 valine, alanine등의 아미노산 분자를 이용하여 수용성 ZnS 나노입자를 합성하였다. 얻어진 고체 생성물들은 XRD, HR-TEM, 및 EDXS분석으로 그 특성을 조사하였다. HR-TEM image 분석의 결과 크기가 대략 3.3에서 3.6 nm 의 입자들이 만들어 졌음을 확인 할 수 있었으며, 나노 입자 표면의 아미노산 분자들은 FT-IR 과 FT-Raman spectrum 을 얻어 결합 모드 등을 분석하였다. Water soluble ZnS nanocrystals were synthesized by capping the surface of the nanocrystals with valine and alanine molecules, which are structurally simple and bio friendly amino acids. The obtained ZnS nanocrystal powders were characterized by XRD, HR-TEM, and EDXS spectroscopies. The measured particle sizes by HR-TEM images were in the range of 3.3 to 3.6 nm. In addition, the surface capping amino acids molecules were characterized by FT-IR and FT-Raman spectroscopies.
