Multiphoton fluorescence microscopy, in which a fluorophore absorbs more than one photon and emits light at a shorter wavelength than the excitation source, can be used to create 3D tissue images at depths of 1 mm or more.  Researchers at the University of Twente have designed a tiny needle in which micro-channels can be used for extracting small liquid samples from a local area of the brain.  The ability to grow large protein crystals is the single biggest bottleneck that limits the use of neutron protein crystallography in structural biology.
