Abstract: A method of manufacturing the calcium nanohydroxyapatite Ca10(PO4)6(OH)2 structurally modified with Li+ ions (nHAP:Li+) Li0.1Ca9.9(PO4)6(OH)2 optionally doped with 1-2% mol of Eu3+ cations in the form of nanocrystalline powder and use of Li0.1Ca9.9(PO4)6(OH)2 in regenerative medicine as an agent improving of proliferative activity of progenitor cells and demonstrating an anti-apoptotic effect on progenitor cells and in addition use of Li0.1Ca9.9(PO4)6(OH)2 doped with 1-2% mol Eu3+ cations as an agent improving of proliferative activity of progenitor cells and demonstrating the luminescence signal used in diagnostic application.

Abstract: A source of white light constructed of a vacuum glass chamber, containing an optically active element, a generator of an IR electromagnetic radiation beam equipped with a laser IR diode, a battery, a focusing lens, and, optionally, a reflector characterized in that the optically active element contained in the vacuum chamber is a thin layer graphene matrix with the thickness of up to 3 mm Embodiments also relate to a method of white light generation by the above-mentioned white light source.
