The Lotus flower • Water & dirt repellancy: solubility? Polarity & Physical PropertiesOzone and Water 0.1278 nm • Resultant Molecular Dipoles > 0 • Solubility: Polar molecules that dissolve or are dissolved in like molecules
The “Lotus Effect” Biomimicry • Water not only dissolves some dirt, but attracts and removes it like a snowball rolling downhill. • Lotus petals have micrometer-scale roughness, resulting in water contact angles up to 170° Wax
The “Lotus Effect” Biomimicry • Isotactic polypropylene (i-PP) melted between two glass slides and subsequent crystallization provided a smooth surface. Atomic force microscopy tests indicated that the surface had root mean square (rms) roughness of 10 nm. • A) The water drop on the resulting surface had a contact angle of 104° ± 2 • B) the water drop on a superhydrophobic i-PP coating surface has a contact angle of 160°.

Amino Acids Legos of Chemical Biology Amino acids contain carbon, hydrogen, oxygen,and nitrogen, which resemble the following shapes & structural components • 20 different amino acids are encoded by the genetic code, which is archived in DNA. • Hundreds of amino acids link together with amide (peptide) bonds to form proteins, which are the machinery for the chemistry of life. • There are less than 20,000 total proteins produced from humans’ entire genome, each coded by a specific gene in DNA’s ~3 billion genetic bases.
Proteins: Indispensible Biopolymers Acetylcholinesterase (ACE) ACE, an enzyme, which catalyzes a key reaction in a repetitive biochemical cycle that is crucial to neurological and physiological functions in humans…. and insects among others. 4,496 atoms; 4,404 bonds 574 amino acid residues
Protein Receptors & Small MoleculesAcetylcholinesterase Enzymes have receptors for small molecules that only have the right shape, which bind with the protein and chemically react. http://chemconnections.org/general/movies/richard.mpg

Historical view of a few smell receptors. 4 October 2004 The Nobel Assembly at Karolinska Institutet has today decided to award The Nobel Prize in Physiology or Medicine for 2004 jointly to Richard Axel and Linda B. Buck for their discoveries of "odorant receptors and the organization of the olfactory system"
