Magnesium is proving itself as a new generation metallic biomaterial which has the natural ability to biodegrade itself due to corrosion when made to interact with human tissues along with aqueous body fluid to treat, improve or replace anatomical elements of the human body. Magnesium based implants serves as temporary scaffold when they are placed in vivo and vitro which acts as temporary support for the part to be healed and was found that the healing took at a faster rate. After a deep search studying and observing different study work it was found that these implants were physiologically compatible, nontoxic, cytocompatible and stimulates bone growth with other favorable characteristics. Magnesium based alloys are very much helpful in different structural body parts such as orthopedic, dentistry, cardiovascular, craniofacial, otorhinology. Main concentration of this review was to discuss some of the more commonly available and frequently used methods for development of bio implant materials and their strengthening mechanism. This review work puts a light on the summary of magnesium based material development for different biomedical applications, with their biocorrosion behavior with advantages, weaknesses and characteristics, as well as a biological translation for these results. This will help the new researchers, scientists, scholars to find a better light material as bioimplant which are in them biodegradable and reduces the pain of secondary surgery.

A simple and efficient synthesis of silver nanoparticles (AgNPs) is reported here using red Dianthus caryophyllus flower, acting both as reducing and capping agent. The resultant silver colloids were characterized using UV-visible spectrophotometer, X-ray Diffractometer (XRD) and Transmission electron microscope (TEM). The surface absorption plasmon response and kinematics of reduction of silver ions were observed by UV-visible spectroscopy. The crystalline fcc structure of AgNPs was confirmed by its XRD pattern. Their morphological study was done with TEM, showing spherically shaped AgNPs in the range 10-20 nm. The antibacterial action was also studied using Agar well diffusion method against pathogenic bacteria cultures (Staphylococcus aureus, Bacillus cereus and Escherichia coli). AgNPs showed better antimicrobial activity against S. aureus culture. Copyright © 2018 VBRI Press.
