Objective(s): Lead is a very strong poison in the environment. Lead toxicity can be affected on the human body and caused disease. Therefore, the design of lead sorbent can be had the great help to the medical field. In this work, the nanohydroxyapatite (n-HA) was used for removal of lead from aqueous solution. Then, polycaprolactone (PCL) nanocomposite was modified with n-HA by simple preparat...

Incorporation of nanohydroxyapatite (nHAP) within a chitosan (CS)/silk fibroin (SF) nanofibrous membrane scaffold (NMS) may provide a favorable microenvironment that more closely mimics the natural bone tissue physiology and facilitates enhanced osteogensis of the implanted cell population. In this study, we prepared pristine CS/SF NMS, composite CS/SF/nHAP NMS containing intrafibrillar nHAP by...

The biological effects of nanohydroxyapatites and its cell toxicity have been studied using the MTT and ALP method, infrared spectrum of absorption and electrophoresis method, respectively. The nanohydroxyapatites are prepared and made by using sol-gel method, in which the parameters of process and reaction are controlled as: pH > 9, Ca/P = 1.67, sintering temperature of 1100 degrees C and sint...

As it is known, the ceramic and metallic materials, such as Ni-Cr and Co-Cr alloy serve often as a fixed dental materials of restoration in human bones, teeth and vascular stents, but they have a lot of shortcomings, such as they can result in Ni and Cr hypersusceptibility of men and ion exchange between the material and tooth, which lead the distortion and discoloration of the gingival edge an...

Fluoride pollution of water is a matter concern in many countries due to its association with chronic kidney failure. Therefore, it important develop fast and efficient methods for fluoride removal from drinking using environmentally friendly materials. In this article, the synthesis, characterization microwave assisted accelerated by porous nanohydroxyapatite (PHAP) are reported. The PHAP samp...
