Use very small tweezers. Nano-tweezers (available from eBay) are a range of specially designed tweezers for handling nanometre size components. (But you will also need to buy some Micro-tweezers to hold the Nano-tweezers. Bit of a scam really.)

Excerpt from Wiki - A blue laser is a laser that emits electromagnetic radiation with a wavelength between 360 and 480 nanometres, which the human eye sees as blue or violet. Blue beams are produced by helium-cadmium gas lasers at 441.6 nm.
