Do neurons have receptors that are not chemical synapses?

[Dory]

Simple question,

I'd like to know whether neurons have receptors that are not chemical synapses? Or, are all neurons receptors chemical synapses?

(I'm constantly thinking about how to nanotechnologically construct a neuron. Defintiely got my work cut out to me. I got a neurobiology guide to understand the neurons/brain better.)

I don't have an answer, just another question. Why would the need for a chemical synapse mean that an artificial (nano-) neuron wouldn't be possible ?
Do you want the artificial neuron/synapse to interact with real neurons ?

[Tero]

No.

All proteins bind all sorts of things, but unless tgis binding triggers something, we do not call it a receptor. An inhibitor might bind in a new site near the regular binding site in such a way it blocks the real substrate binding.

Erm...

Some receptors are part of a chemical synapse.

No because quantum effects decohere at temperatures anywhere near body temperature extremely rapidly. So any signal would degrade so rapidly as to be meaningless noise. There are quantum effects on the human body, such as in smell so I hear, but signalling is not one of them. Or at least there is no scientific data to suggest there is. I got a week off from a physics forum once for posting a speculative paper on this that was not in the right journals. It makes physics bods cranky and tends to elicit the crackpot word. Penrose and Hameroff are current proponents google that.
