The novel properties of nanomaterials also encourage their use to improve the growth of different tissues. Nano structured ceramics can be synthesized; thus, they may have particle size, geometry and microarchitecture similar to physiological bone. In this study, mechanical and bioactivity properties of nanohydroxyapatite (nHA)-nano magnesium oxide (nMgO) and nano hydroxyapatite (nHA) -nano niobium (V) […]

In this work, we have investigated the self-assembled monolayer (SAM) of L-cysteine on Au(111) and its application in electrochemical oxidation of uric acid by scanning tunneling microscopy (STM), cyclic voltammetry (CV) and differential pulse voltammetry (DPV). Monolayer of L-cysteine on Au(111) was observed, which shows that single monolayer of L-cysteine was formed on Au(111). Oxidation […]

Sergey V. DOROZHKIN, Nanometric calcium orthophosphates (CaPO4): preparation, properties and biomedical applications, Advanced Nano-Bio-Materials and Devices; 2019:3(4):422-513

Nanometric particles and crystals play very important roles in biological systems. For example, calcium orthophosphates (abbreviated as CaPO4) of nanometric dimensions represent the basic inorganic building blocks of bones and teeth of mammals. According to recent discoveries in biomineralization, zillions nanometric crystals of biologically formed CaPO4 are nucleated in body fluids and, afterwards, they are […]

Sergey V. DOROZHKIN, Self-setting calcium orthophosphate (CaPO4) formulations and their biomedical applications, Advanced Nano-Bio-Materials and Devices; 2019:3(3):321-421

In early 1980-s, researchers discovered self-setting calcium orthophosphate (CaPO4) formulations (initially known as calcium phosphate cements), which were bioactive and biodegradable grafting bioceramics in the form of a powder and a liquid. After mixing, both phases formed pastes of variable viscosity, which set and hardened forming most commonly a bone-like non-stoichiometric calcium deficient hydroxyapatite (CDHA) […]

The hyaline cartilage of the joint present high susceptibility to traumatic injury and degeneration and the ability of this tissue to regenerate is limited. Using a rabbit experimental model, our aim was to assess the Biomimetic scaffold capacity to recover the damaged cartilage by evaluation of Hounsfield Units (HU) on Computed Tomography scan. The biomimetic […]

Additive manufacturing techniques like robocasting have a great potential for the fabrication of scaffolds for bone regeneration and tissue engineering. The goal of this study was to produce undoped and ion (Sr2+ and Mg2+) doped biphasic calcium phosphate (BCP) scaffolds by robocasting. The powders were prepared by hydrothermal synthesis (150ºC, 4 h), calcined at 1000ºC, […]

Hip arthroplasty consists of a series of sequential manipulations, one of them is the femoral neck osteotomy. The position of the implant and the presence of postoperative complications depend on accuracy of this technique implementation. The purpose of the study was to develop a device for the femoral neck osteotomy. The study was designed to […]
