Towards Experimental Tests of Quantum Effects in Cytoskeletal Proteins
  It has become increasingly evident that fabrication of novel biomaterials through molecular self-assembly is going to play a significant role in material science and possibly the information technology of the future. Tubulin, microtubules (MTs) and the cytoskeleton are dynamic, self-assembling systems and we asked whether their structure and function contain the clues on how to fabricate biomolecular information processing devices.   Here we review our neurobiological studies of transgenic Drosophila that strongly suggest the microtubular cytoskeleton is near the 'front lines' of intracellular information manipulation and storage. We also establish that spectroscopic techniques such as refractometry, surface plasmon resonance sensing and dielectric spectroscopy, coupled with molecular dynamic simulations and (quantum) electrodynamic analytical theory are useful tools in the study of the electrodynamic and possible quantum effects in cytoskeletal proteins.   Implicit in our driving question is the possibility that if tubulin and MTs can indeed be cast as the basis of a classical or quantum computer, then perhaps nature has already done so and tubulin and MTs already play such a role in living neural and other cells. If quantum mechanics is found to be important in cellular function (through its involvement in proteins) it is natural to ask whether there are indeed quantum effects pertinent to consciousness. We conclude this work by suggesting a number of ways towards experimentally testing this "Quantum Consciousness Idea" (QCI), directly at the protein level.
