Two principal approaches<br />
<strong>Top</strong>-Down<br />
Miniaturizing existing<br />
processes at the<br />
Macro/Microscale<br />
Traditional approach in<br />
industrial applications<br />
E.g. Lithography, backbone of<br />
computing systems<br />
<strong>Bot<strong>to</strong>m</strong>-Up<br />
Assembling structures from<br />
the a<strong>to</strong>mic/molecular level<br />
Novel approach, conceptually<br />
imitating nature<br />
E.g. chemical self-assembly<br />
