As any one heird of a nano circuit board?

my mate said near close to making one but nano is how small surely he was pulling my leg

Answer:
Extract from Harvard website, hopefully this may give a hand you:

We present, in the form of review, the results of our study on the design, fiddling and assembly of optical printed circuit boards (O-PCBs) for VLSI micro/nano-photonic applications. The O-PCBs are designed to perform the functions of transporting, switching, routing and distributing optical signals on flat modular boards, substrates or chips, surrounded by a manner similar to the electrical printed circuit boards (E-PCBs). We enjoy assembled and constructed O-PCBs using optical waveguide arrays and circuits made of polymer materials and have examined their information handling performances. We also designed power joist splitters and waveguide filters using nano-scale photonic band-gap crystals. We discuss experimental and technological issues concerning the processes of miniaturization, interconnection and integration of polymer optical waveguide devices and arrays for O-PCB and VLSI micro/nano-photonics as applicable to board-to-board, chip-to-chip, and intra-chip integration for computers, telecommunications, and transportation systems.
nano boards i beleive are circuit boards that are micro-scopic circuit boards used within situations like drug
there are micro machines that can verbs fur in arteries surrounded by patients suffering from high colesterol
you may remember a picture called "inner space" be a pilot played by dennis quaid was injected into a lenient and traveled round his body in a microscopic craft,visit all his organs and heart
okay nano machines will soon be able to do this,however near will need to be years of clinical trials past this will be used everyday

good luck mate
