The aim of the work is to compare the properties of nanohydroxyapatite coatings containing antibiotic - gentamicin or silver nanoparticles. The coatings were obtained using the electrophoretic deposition method (EDP). The additives were introduced by the immersion method.

Unfortunately, the emergence of lifestyle diseases such as osteoporosis, which is characterized by a decrease in the biological value of bone tissue, a greater number of road accidents and related injuries to the musculoskeletal system, and the increasing expectations of people with degenerative polyarticular changes to remain mobile, have significantly increased the demand for all types of implants and prostheses. Bone fixations pose a serious challenge for doctors, especially when the bone is also osteoporotic.

The primary sedimentation was used to minimize the risk of the formation of particle agglomerates on the sample surface. Evaluation of the coating was performed by using a Scanning Electron Microscope (SEM), Energy-Dispersive Spectroscopy (EDS), Atomic Force Microscopy (AFM), optical profilometer, drop shape analyzer, and a nanoscratch tester.

Over time, these pathogens, particularly bacteria, can colonize the stent surfaces, leading to various complications. Two weeks following the stent insertion procedure, the colonization becomes observable, with the aggressiveness of bacterial growth directly correlating with the duration of stent placement.

The unique properties of the coating depend on the ratio of the sp/sp phases, where the sp phase provides coatings with a low coefficient of friction and good electrical conductivity, while the share of the sp phase determines the chemical inertness, high hardness, and resistance to tribological wear. DLC coatings are characterized by high hardness, low coefficient of friction, high corrosion resistance, and biocompatibility.

Cemented arthroplasty is a common process to fix prostheses when a patient becomes older and his/her bone quality deteriorates. The applied cements are biocompatible, can transfer loads, and dampen vibrations, but do not provide antibacterial protection. The present work is aimed at the development of cement with antibacterial effectivity achieved with the implementation of nanoparticles of different metals.

One of the most efficient ways of reducing tire/road noise is to use the so-called "low noise pavement". According to numerous studies, at present, poroelastic road pavement that is composed of rubber and mineral aggregate and polyurethane or bituminous binder gives the best noise reduction up to 12 dB.

Fractures in the craniofacial region are a serious problem in terms of treatment. The most reasonable solution is the use of individual implants dedicated to a specific patient. The aim of this study was to develop the implant system specifically for treatment of the orbital floor defects of blowout fractures of maxillofacial region, using polypropylene yarn and bone cement.

This study aimed to assess SSI after breast surgery over five years in a single center in Poland. The microorganisms responsible for SSI and their antibiotic susceptibilities were determined.

This study aimed to investigate whether the incorporation of gentamicin or nanometals into bone cement may reduce and to what extent bacterial growth without the loss of overall cytocompatibility and adverse effects in vitro. The bone cement Cemex was used as the base material, modified either with gentamicin sulfate or nanometals: Silver or copper.
