Document Summary
: is the use of what is learned from nature to design new. What happens at the molecular level that gives gecko feet spider-man like. Atoms and molecules are too small to see. Non covalent intermolecular interactions between the gecko"s feet and the surfaces allow its adhesion to surfaces. Scanning electron microscopy shows that the gecko feet has thousands of hair like structures called setae, each hair has a bump that ends in a rounded hydrophobic tip. The size, shape and polarity allow the gecko to use non covalent interactions to stick to dry smooth surfaces. (forces of attraction are weak, and can be broken easy) They differ in the sign of their rotation of plane-polarized light and in odour. ___9. 2 experimental tools for molecular structures and shapes__ Example: spearmint and caraway oil, smell the way they do because they both. Shapes aren"t static change as a result of rotation about bonds.
