An amphiphilic polymer, poly[(aminoethyl methacrylate)-co-(butyl methacrylate)] (PAMBM), inspired by antimicrobial peptides, was bactericidal against S. aureus in time-kill experiments. PAMBM was then evaluated in a variety of polymer blends using the Japanese Industrial Standard (JIS) method and showed excellent, Antimicrobial Agents I. of handling, they are used in preference to gaseous chlorine. These agents retain chlorine longer and have a prolonged bactericidal action. Chlorinated lime (bleaching powder) is obtained by the action of chlorine on lime.

Nanotextured surfaces (NTSs) are critical to organisms as self-adaptation and survival tools. These NTSs have been actively mimicked in the process of developing bactericidal surfaces for diverse biomedical and hygiene applications. To design and fabricate bactericidal topographies effectively for various applications, understanding the bactericidal mechanism of NTS in nature is essential. The combination of UV with electrical components of the positive DC corona ex- erted a significant bactericidal effect that caused total elimination of 105 CFU within less than 120 s. Bactericidal activity of UV produced by the positive DC corona was considerably lower than the activity of combined action of two or three active agents [Fig. 5(A)].
