SUMMARY

Designing molecules that can rearrange in response to electromagnetic signals, particularly radio frequencies, presents significant challenges due to the size of the wavelengths involved and the thermal fluctuations at conventional temperatures. The discussion highlights that at lower frequencies, thermal noise can randomize molecular arrangements unless cooled to near single-digit Kelvin temperatures. Nature has evolved temperature-sensitive sensory components in organisms, such as the heat vision of pit vipers, which involve protein reconfigurations but do not directly respond to infrared signals. The concept of moths detecting pheromones through infrared colors has been largely discounted due to these thermal equilibrium issues.

PREREQUISITES
  • Understanding of electromagnetic spectrum and molecular interactions
  • Knowledge of thermal dynamics and temperature effects on molecular behavior
  • Familiarity with protein structure and function in biological systems
  • Basic principles of sensory biology and organismal adaptations
NEXT STEPS
  • Research molecular design techniques for temperature-sensitive materials
  • Explore the principles of thermal fluctuations in molecular systems
  • Investigate the mechanisms of infrared sensing in biological organisms
  • Study the effects of cooling techniques on molecular stability and behavior
USEFUL FOR

Researchers in molecular biology, materials science, and sensory biology, as well as anyone interested in the intersection of chemistry and electromagnetic signal response.

Hi everyone,

I'm wondering if its possible to design a molecule that re-arrange on an electromagnetic (non-visible and radio) signal, and revert back to original structure when signal stops.

Thanks in advance

Two problems with this.
Firstly you're talking about wavelengths orders of magnitude larger than typical molecules and even whole biological cells.

Secondly at these lower frequencies you are near or below the peak freq. for thermal spectrum at conventional temperatures so unless the molecule is cooled down near single digit Kelvin temperatures, the background thermal fluctuations will randomize any arrangements you're considering.

Likely what is possible has been evolved in nature. (... pause for google searches...)

Consider the temperature sensitive sensory components of many organisms. Your sense of tactile warmth and more selectively a pit viper's heat "vision" must involve protein reconfigurations at the sensor cells. However this is not a direct effect but rather the infrared produces heat which is sensed. [See:http://www.nature.com/nature/journal/v464/n7291/abs/nature08943.html" ]

Phillip S. Callahan suggested moths may detect pheromones from their infrared "colors" but this has pretty much been discounted by the very argument I gave with regard to thermal equilibrium issues. [see: http://www.jstor.org/pss/76364"]
