@alexchiniborch: The coloured line on a pregnancy or rapid test is real gold — microscopic colloidal-gold nanoparticles. The same metal we have trusted for 5,000 years now sits inside modern medicine. Save this. Compliance: Gold in medical testing and research is presented for education only; this carousel does not provide medical advice or make treatment claims. Not financial advice. Metals carry risk. #TheGoldGuyDubai #Gold #Science #Nanoparticles #GoldFacts #Dubai #Medicine #Bullion #DidYouKnow #StoreOfValue
