It is kinda hard to answer without the answers, huh? Heres the possible answers for this Question!

radio

infrared

gamma

ultraviolet

(at least for my test, dont know about others)

in situ hybridization has been widely used for research applications, including clinical cytogenetics, gene mapping, tumor biology and studies of chromosome evolution.

micro/nanoscale topography surface exhibits many prominent properties and is extensively employed in biomedical device, microfluidic device and energy device fabrication. additionally, the clinical applications of biomaterials can be largely expanded with of nanostructured surfaces.
