The impact of Cu(II) ions doping in nanostructured hydroxyapatite powder: A finite element modelling study for physico-mechanical and biological property evaluation

Biodegradable manganese-doped hydroxyapatite antitumor adjuvant as a promising photo-therapeutic for cancer treatment

“…The phosphate group’s v3 stretching mode is responsible for the peak at 1,041 cm −1 . Peak P-O tension ν1 stretching took place at 966 cm −1 ( Park et al, 2022 ). The v4 bending vibration based on the phosphate group is shown in the peak at 573 cm −1 .…”

“…Set the pH of the combined solution to 9 and stir for 6–8 h at 180 rpm. Deionized water was used to rinse, dry, and then calcine the synthesized product for 1 hour at 600°C from the acquired precipitates ( Park et al, 2022 ).…”

“…The animals in group II demonstrated a maximum temperature increase of 1.6 °C after being exposed to a 0.75 W cm −2 laser (808 nm) for 7 min, resulting in a final body temperature of 32.2 ± 0.7 °C. The laser dosage alone was unable to raise the temperature because there were no nanoparticles present inside the target tumor location (Mondal et al, 2022). Intratumorally injected with 100 μl of a 200 μg/ml 2.0 mol% Mn-HAp/FA-IR-783 solution, Group V animals were then subjected for 7 min to a 0.75 W cm −2 laser (808 nm).…”

Enhancement of photocatalytic efficacy by exploiting copper doping in nano-hydroxyapatite for degradation of Congo red dye

“…The linear form of the Langmuir adsorption isotherm can be expressed as eqn (19). 57 Table 2 First order rate constant (K 1 ) and regression coefficient (R 2 ) of the prepared samples at doses of 0.1 and 0.2 g of photocatalyst Sample ID For 0.1 g of photocatalyst For 0.2 g of photocatalyst Another dimensionless equilibrium parameter (R L ) can be calculated from the Langmuir adsorption constant (K L ) and mathematical expression of eqn (20).…”

“…in a composite or doped form. [12][13][14][15][16][17] Copper is another doping element for the HAp crystal and has recently been used in Fenton-like Cu doped HAp either alone or in combination with other elements, 10,18 in polycaprolactone encapsulated HAp, 19 to enhance biocompatibility, 20 etc.…”
