 irect probes for nodes in the superconducting order parameter of novel com
 pounds are highly desirable since it helps in a rapid development of possi
 ble applications of the material. Vortex imaging with scanning tunnelling 
 microscopy is one direct probe for anisotropic order parameter since in mo
 st anisotropic superconductors the spectroscopic halo of vortices is elong
 ated\, but this probe is limited to the high magnetic fields range. In the
  case of low and intermediate fields\, direct imaging of the magnetic halo
  of vortices can be performed by several techniques based in the detection
  on changes of the local field gradient entailed by a vortex. Nevertheless
 \, in many superconductors with anisotropic order parameters the shape of 
 vortices is not necessarily observed as deformed using these magnetic imag
 ing techniques. Thus\, finding another direct probe for anisotropic order 
 parameters applicable in low as well as high fields would be most valuable
 . In this talk I will present one probe based in the experimental observat
 ion of changes in the structural properties of vortex matter induced by th
 e confinement in micron-sized samples due to the  material presenting node
 s in the order parameter.
