Abstract:
Antibacterial activity is essential and highly demanded in worldwide to prevent potential bacterial infection. Here in this work, we report a new approch for the fabrication of flexible zinc oxide nanopillar arrays (ZG-NPA) film with an efficient antibacterial activity. A flexible NPA film served as a substrate for the rapid formation of ZnO by using ultrasound-assisted method. The enhancement of antibacterial activity were induced by cellular damages because of nano topological effects and electrostatic interaction between bacteria and ZG-NPA. Owing to the benefits of combination with flexibility, high surface areas from nano-features and excellent antibacterial efficiency (>80%) of ZG-NPA, the film can show great potential for use as novel biomaterials for preventing bacterial infections.

Globular and Fibrous Proteins
Globular proteins are also known as spheroproteins and typically are approximately round in shape. They contain a mix of amino acid types and contain differing sequences in their primary structures. Globular proteins have many different functions, such as enzymes, cellular messengers, and molecular transporters. These roles often require the proteins to be...
