For analysis of the sensing properties, analyze the morphology of the sample with AFM. As analyzing its electrical properties, measure time-variant IV shifting curve for analyzing sensing reactivity of the samples by electrical methods; cyclic voltametric measurements.

Result
1. Morphology of MWCNT biosensor surface
(1) Iconic: symbol of something developed from drawing
1) Pictograph : essentially a drawing of an object.
= sun
= heat
light
daytime
warmth
(2) Noniconic: Symbols in a writing system
1) Morphographic writing : each symbol represents a single morpheme.
2.3. Compound retrieval
When using compound word, we can separate similar images such as sky and sea. This word is hard to be separated by color or shape. Text can be a useful vehicle by searching images. For example, we typed word 'blue', 'snow', and 'tree'. Although Google image retrieval is based in keyword and idee visual search lab is based in tag, we can get result which is similar to res
Advantage
Bridge the semantic gap between users and retrieval system
Disadvantage
No one-to-one correspondence between words and meanings
Text-based image retrieval should be developed with the content-based image retrieval.
엽록소를 가진 식물체에 널리 존재한다. 전분은 식물의 씨·뿌리·줄기·알뿌리·열매 등에 함유된 중요한 저장물질의 하나이며, 고등동물에서도 탄수화물의 주요 공급원으로 서로 다른 두개의 성분으로 구성된 고분자 물질이다. 전분은 식물의 광합성에 의해 물과 이산화탄소로부터 합성되어 입자형태
