Molecular Structures & Designed Materials

Apply Voltage:

Structure & Function

Structure: Metals form a lattice of positive ions surrounded by a "sea" of delocalized electrons.

Function: Because these electrons are free to move, applying a voltage causes a net drift of charge. This molecular-level structure makes metals excellent electrical conductors.

Controls

Apply Stress (Pulling Force): 0%

Structure & Function

Structure: Polymers are composed of very long, chained molecules that can become tangled or coiled.

Function: When stress is applied, these long chains can uncoil, straighten, and slide past each other without breaking the strong covalent bonds. This makes them flexible but highly durable.

Controls

Test which drug molecule fits the target cellular receptor.

Structure & Function

Structure: Pharmaceutical molecules have highly specific 3D geometric shapes and charge distributions.

Function: Drugs must fit perfectly into specific cellular receptors (the "lock and key" model) to trigger or block a biological response. Only the correct molecular structure functions properly.
