Explanation:

• These are a new type of gold in the form of very small crystals developed by researchers from Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR), Bengaluru.
• The microcystallites were synthesised by decomposing an organic complex containing gold and other ions under controlled conditions.
• The microcrystal gold has been found to be nobler than gold — it do not dissolve in mercury and Aqua regia (a mixture of nitric acid and hydrochloric acid), and showed the least interaction with copper.
•  Microcystallites are also more stable than the normal gold.
