Walking Molecules!

Nanomotors are used throughout biology to perform tasks. Spectacular examples include the motor protein myosin that makes muscles contract by "walking" along molecular tracks in the cell. 

Professor David Leigh's group have made the first synthetic walking molecules that move directionally along molecular tracks. The ultimate goal of such research is to produce artificial molecular vehicles that can transport cargoes and perform other complex tasks at the nanoscale. 

However, such 'molecular engineering' is not easy: at the molecular level gravity is too weak to hold the walkers onto tracks and special molecular glue, footholds and attachment points all have to be carefully designed to make a successful walking molecule (see video).

Thank you for writing to "Chemical Science"

Message from Bhagavath Geetha
  • Do not get over excited over happiness and do not get over depressed over sorrow.
  • Do not get over bonded with anyone and anybody because it can lead to problems and sorrow.
  • Never think that my duty is the topmost or lowermost. Every duty is respectful. The responsibility undertaken or given as per the position is the noblest duty.
  • Elevate yourselves, family, society and nation and never denigrate yourselves, family, society and nation.
  • We are our own closest relatives and if not properly utilised we will become our closest enemies.
  • There are possibilities of success and failure in any endeavour. One cannot assure success always.
  • Death is inevitable for everyone in this world. In any endeavour at the maximum an individual may die.
  • People may say good and also they may say bad. Approach them with stabilised mind.
  • Take anything after scientifically, logically and rationally analysing them.
  • Perform your duty, responsibility and accept the privileges eligible for you.
  • First change ourselves and then try to change others.
  • We are all instruments /tools in the hands of the nature for performing the duty. So do not think that I am doing the duty. Think that I am an instrument to do the duty.

  • Follow the path of great scholars who guided the world. Listen their messages.
  • Results and rewards will come and go but stick to your duty with devotion, dedication and sincerity.
