2.3.2 Counter Ion “Most bacterial cell walls are charged with a negative charge‚ so most antibacterial polymers must be charged with a positive charge to facilitate the adsorption process. The composition of the counter ion‚ or polymer-linked ions‚ is used to balance the charge‚ it also affects the antibacterial activity. The counter ion has positive charge‚ which is a strong ion-pair with the polymer will inhibit the antibacterial activity because it will prevent the polymer from interacting with

4 Plasmon Resonances for PS@Au-Cu-Ag Composite Nanoshells 4.1 Introduction As shown in recent studies‚ various methods have been developed to expand the application area of noble metal nanoparticles and to control the morphology and the behavior. Composite microspheres with noble metal nanoshells have great advantages in catalysis‚ optics‚ conductivity‚ chemical sensors‚ and so on [1–5]. Moreover‚ these hybrid materials can prevent noble metal nanoparticles from agglomerating without the use of

1.CANCER Cancer /ˈkænsər/‚ known medically as a malignant neoplasm‚ is a broad group of diseases involving unregulated cell growth. In cancer‚ cellsdivide and grow uncontrollably‚ forming malignant tumors‚ and invading nearby parts of the body. The cancer may also spread to more distant parts of the body through the lymphatic system or bloodstream. Not all tumors are cancerous; benign tumors do not invade neighboring tissues and do not spread throughout
