Therefore the whole atom is neither positive nor negative. 因此，整個(gè)原子，既不帶正電，也不帶負電。
The positive nanocapsule can interact with the negative biomembrane, resulting in targeted delivery on specific sites. 帶正電的奈米膠囊，可與帶負電的生物膜交互作用，而達到特定位置之標靶投藥。
Electrons are negatively charged with electricity. 電子帶負電荷。
Each electron bears a single negative charge. 每一個(gè)電子都帶有一個(gè)負電荷。
