Cobalt Ions Doped Bioactive Ceramics for Biosensor Biomedical Applications

Abstract

Cobalt ions doped hydroxyapatite (Co-HAp) was synthesized by ultrasonication assisted co-precipitation route. The phase of HAp was confirmed by XRD analysis. The crystallite size of doped sample was reduced (28%). The functional groupsof HAp were confirmed by FTIR and Raman analysis. Cobalt ions doped samples were showed magnetic behavior. In addition, optical properties of the samples were also carried out. Hence, cobalt ions doped samples could be an excellent candidate in biosensor and biomedical fields.

Monte Carlo Simulation of TRIM Algorithm in Ceramic Biomaterial in Proton Therapy

“…Ceramic materials used as biomaterials in this study, namely, alumina (Al 2 O 3 ), silicon dioxide (SiO 2 ), titanium dioxide (TiO 2 ), and zirconium dioxide (ZrO 2 ) were simulated by MC TRIM to be compared with bone tissue. Mass densities (g/cm 3 ), atomic number density (×10 22 atoms/cm 3 ), and basic chemical compositions in percent (%) of ceramic biomaterials are given in Table 1. The TRIM simulation program determined these percentages according to the ICRU-276 report [26].…”

“…They are preferred over metal-based biomaterials because of their excellent biocompatibility, poor degradability, high melting temperature, non-corrosive, better mechanical properties, and poor plasticity [ 16 ]. Bioceramics are hard and brittle and have low fracture toughness with elastic modulus compared to bone [ 12 , 22 , 23 ]. Synthetic bioceramics such as alumina, zirconia, titania, and bioactive glasses/glass ceramics are used in dentistry, orthopedics, calcified tissues, implants, coatings, medical sensors, and many other applications [ 24 ].…”
