<p>Abstract<br />Biphasic calcium phosphate (BCP) widely used as implants and scaffolds in different orthopedic and dental application. The aim of this study was to determine synthesis and characteristics of biocomposite BCP/collagen as bone scaffold material. BCP/collagen was classified into three groups: 1) BCP/K5 (5% collagen in scaffold), 2) BCP/K10 (10% collagen in scaffold), and 3) BCP/K15 (15% collagen in scaffold). The samples were characterized by Fourier Transform Infrared (FTIR) Spectroscopy, and Scanning Electron Microscope (SEM) techniques. Overall, concentration of collagen was not significantly different to the spectrum. However, FTIR analysis shows the change intensity in bio-composite BCP/collagen. Collagen intensity Higher concentration when collagen concentration in scaffold higher. Morphology analysis of the scaffold showed significant differences in pore formation. BCP/K15 was showed pores formed in scaffold. Synthesis of composite BCP/collagen does not affect the spectrum of functional groups, but affects the formation of pores in the bone scaffold material.</p>

The increasing production of cuttlefish has been associated with the increasing of by-product waste particularly cuttlebone. Cuttlebone is known to contain an inorganic element in form of calcium carbonate<br />(CaCO3) which can be utilized as a source of calcium oxide (CaO) for hydroxyapatite synthesis. This study was aimed to determine the physicochemical characteristics of the cuttlebone and the optimum calcination temperature for CaO extraction and hydroxyapatite synthesis. This study was divided into three steps. Firstly, analysis of the cuttlebone physicochemical properties; secondly, extraction and characterization of the CaO with different calcination temperature (500°C, 600°C, 700°C for 6 hours); and thirdly, hydroxyapatite synthesis using a combination of hydrothermal method at 200°C 6 hours and different calcination treatments (800°C, 900°C, 1,000°C for 1 hour). The results showed that the cuttlebone contained moisture 3.54±0.11%,<br />lipid 0.32±0.19%, protein 4.78±0.23%, carbohydrate 5.29±0.02%, and ash 89.61±0.26. The main element of the ash was CaCO3 aragonite characterized by the high absorption at wavelengths of 1,795; 1,507;<br />1,083; 871; 713 and 700 cm-1. The calcination treatment of 700°C produced the highest amount of CaO. The hydroxyapatite produced with a combination of hydrothermal and calcination temperature 1,000°C<br />had calcium phosphate ratio (Ca/P) 1.66, crystalline level 90.10%, amorphous level 9.90% and particles morphology of rod-shaped.

In order to develop cotton fabric underwear with the health care function, the cotton fiber was modified with the collagen (CMCF) using periodate oxidation method. The aldehyde groups on the glucose chains of the oxidized cotton cellulose were reacted with the amino groups of collagen to obtain the CMCF, and the oxidized cellulose was crosslinked with collagen in aqueous acetic acid media. The effects of collagen concentration, treatment time, reaction temperature, pH value of solution and periodate concentration on the amount of collagen crosslinked on cotton fiber were respectively discussed, and the optimal reaction technology was obtained. XPS characterization of the modified cotton fiber showed a characteristic peak about 400.0–405.0 eV corresponding to collagen, which indicated that the collagen was combined on the surface of cotton fiber. The mechanical properties of the collagen modified cotton fiber were improved. The resulting CMCF is a new natural ecological fiber and has the extensive application as a carrier for the controlled release of drugs.

Coating of iron oxide nanoparticles (MNP) is the common approach to reduce the effects of direct toxicity due to the ion oxidation that lead to the damage of DNA. This study investigates the effect of different concentration of Chitosan (Cs) used to coat the magnetic nanoparticle with variation in the crystallite size, chemical bonding, changes in weight and surface morphology. From the XRD results, it shows that the sample 1MNP-1Cs has optimum size of 13.42 ± 0.01 nm. From the FTIR analysis, it is revealed that there are three types of chemical bonding that occur in the MNP-Cs composites which are stretching vibrations of C-H, N–H vibration belonging to Cs and the Fe-O bonds from the MNP. From the FESEM analysis, it is found that the MNP-Cs composites have a wellshaped with spherical in form, as well as, smooth surfaces. As for TGA, the thermal decomposition of MNP nanocomposites was based on the amount of Cs and MNP used to produce the nanocomposites. Further studies will be conducted to find the optimum ratio of MNP-Cs for anticancer drug delivery application.

Polystyrene is considered stable to biological degradation. Lantinus tigrinus isolated from wood sample produced esterase in growth medium under normal conditions. However, acidic medium, 37 degrees C temperature, presence of tween 80; and urea and yeast extract in mineral salt medium enhance the production of esterase and specific activity. Purified esterase was active at broad pH range and 45 degrees C. FTIR analysis confirmed that esterase produced by Lantinus tigrinus effectively degraded polystyrene film and broke macromolecules down to non-toxic molecules. This study concludes that the presence of Lantinus tigrinus at dumping sites can be exploited for waste management containing high molecular weight synthetic polymers.
