Adhesion and Friction in Biological Systems

About this book

Adhesion and Friction in Biological Systems is a collection of experimental studies demonstrating structure-function relationships in various biological systems having particular surface specialization to increase/decrease friction and adhesion. Studies on snake skin, adhesive pads, wing-interlocking devices and sticky mouthparts of insects as well as anti-adhesive and adhesive surfaces of plants are included in Adhesion and Friction in Biological Systems containing four main subsections: (1) adhesion, (2) friction, (3) attachment-devices, (4) attachment-related behavior. Numerous experimental methods for characterizing tribological properties of biological surfaces at macro-, micro-, and nanoscale levels are demonstrated. Adhesion and Friction in Biological Systems is an excellent collection of publications on biotribology for both engineers and physicists working with biological systems as well as for biologists studying friction and adhesion. Inspirations from biology reported here may be also potentially interesting for biomimetics.
