“…Thus, these modifications also have a considerable impact on the biological response of doped HAp, both in vitro and in vivo . 5 To date, different research groups have reported the synthesis of doped-HAp materials and utilized such materials in a variety of fields including medicine, 6 catalysis, 7 photocatalysis, 8 bone tissue engineering, 9 drug delivery 10 and so on. Out of these, photocatalysis is one of the most widely explored applications of modified hydroxyapatite materials.…”
