A material change for ultra-high precision force sensing
An original form of photonic force microscope has been developed. Operating with a trapped lanthanide-doped crystal of nanometric dimensions, a minimum detected force of the order of 110 aN and a force sensitivity down to 1.8 fN/ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:msqrt><mml:mrow><mml:mi>Hz</mml:mi></mml:mrow> </mml:msqrt> </mml:math> have been realised. This opens up new prospects for force sensing in the physical sciences.
