Abstract

Colloids are a heterogeneous system in which particles of a few nanometers to hundreds micrometers in size are finely dispersed in liquid medium, but show homogeneous properties in macroscopic scale. They have attracted much attention not only as model systems of natural atomic and molecular self-assembled structures but also as novel structural materials of practical applications in a wide range of areas. In particular, recent advances in colloidal science have focused on nano-bio materials and devices which are essential for drug discovery and delivery, diagnostics and biomedical applications. In this review, first we introduce nano-bio colloidal systems and surface modification of colloidal particles which creates various functional groups. Then, various methods of fabrication of colloidal particles using holographic lithography, microfluidics and virus templates are discussed in detail. Finally, various applications of colloids in metal inks, three-dimensional photonic crystals and two-dimensional nanopatterns are also reviewed as representative potential applications.

콜로이드는 거시적으로 균일한 성질을 갖는 입자분산계이다. 콜로이드 입자는 다양한 입자분산계의 모델로서 많은 기초연구가 이루어져 왔을 뿐만 아니라, 산업적으로 다양하게 응용이 되었다. 최근에는 나노-바이오 관련 연구에 적용되어 새롭게 각광을 받고 있는 나노 소재중 하나이다. 본 총설에서는 입자 분산계의 정의 및 분류에 대해 간략히 기술하고, 나노-바이오 응용을 위한 표면 성질 및 표면 개질방법에 대해 다룰 것이다. 또한, 기존의 구형의 입자분산계에서 더 나아가, 모양과 크기가 제어된 입자 분산계의 합성에 관한 최근 결과를 소개하였다. 마지막으로, 콜로이드 입자의 나노-바이오 응용분야로서, 금속 콜로이드 잉크와, 3차원 콜로이드 결정을 활용한 나노-바이오 센서, 및 2차원 콜로이드 구조를 이용한 패턴제작과 응용 연구에 대해 살펴보았다.
