“…The introduction of bioactive agents into degradable or water-soluble synthetic polymers is also reported as an effective strategy . Polylactones and PEGs are effectively used as supportive coatings to carry bioactive agents . The modified polymers are also used to create either substrate-adhering nanofilms or hydrogel-based thick coatings with high bioactivity to stimulate cell adhesion or to avoid microbial adhesion.…”

The study of bacterial adhesion and its consequences has great significance in different fields such as marine science, renewable energy sectors, soil and plant ecology, food industry, and the biomedical field. Generally, the adverse effects of microbial surface interactions have attained wide visibility. However, herein, we present distinct approaches to highlight the beneficial aspects of microbial surface interactions for various applications rather than deal with the conventional negative aspects or prevention strategies. The surface microbial reactions can be tuned for useful biochemical or bio-electrochemical applications, which are otherwise unattainable through conventional routes. In this context, the present review is a comprehensive approach to highlight the basic principles and signature parameters that are responsible for the useful microbial−electrode interactions. It also proposes various surface tuning strategies, which are useful for tuning the electrode characteristics particularly suitable for the enhanced bacterial adhesion and reactions. The tuning of surface characteristics of electrodes is discussed with a special reference to the Microbial Fuel Cell as an example.

“…Bioactive glass (BG) has been commonly studied as a bone substitute due to its outstanding biological properties, such as great binding to newly formed bone tissue and the deposition of a carbonated hydroxyapatite layer on its surface that promotes bone regeneration [1]. The first BG reported in the literature was initially studied by Hench et al [2], BG (45S5 ® ), which allows the artificial organ to effectively fit into the bone cavity [3] and has been gaining space in clinical applications such as Perioglas ® [4] and Ceravital ® [5]. Its first application in orthopedics was approved by the FDA in 2000 [6].…”

Bioactive glasses (BGs) can potentially be applied in biomedicine, mainly for bone repair and replacement, given their unique ability to connect to natural bone tissue and stimulate bone regeneration. Since their discovery, several glass compositions have been developed to improve the properties and clinical abilities of traditional bioactive glass. Different inorganic ions, such as strontium (Sr2+), have been incorporated in BG due to their ability to perform therapeutic functions. Sr2+ has been gaining prominence due to its ability to stimulate osteogenesis, providing an appropriate environment to improve bone regeneration, in addition to its antibacterial potential. However, as there are still points in the literature that are not well consolidated, such as the influence of ionic concentrations and the BG production technique, this review aims to collect information on the state of the art of the biological behavior of BGs containing Sr2+. It also aims to gather data on different types of BGs doped with different concentrations of Sr2+, and to highlight the manufacturing techniques used in order to analyze the influence of the incorporation of this ion for bone regeneration purposes.

“…[3] Beside of the good biocompatibility, excellent chemical resistance and good mechanical properties, it also has a closer Young's elastic modulus to the human cortical bones. [4] Modifying to improve its bioactivity can reduce the rate of implantation failure caused by poor osseointegration and avoid secondary surgeries, reducing the economic burden of the patients. Currently, two strategies are available for improving the bioactivity of polymer including composite preparation (incorporating bioactive materials into polymer) and surface treatment/coating with physical/chemical methods [5] Among these strategies, impregnating bioactive materials into polymer has become an attractive approach for improving the bioactivity while maintaining its mechanical properties.…”

To date, there has been a lot of interest in the development of medical/dental implant materials. Many studies have been conducted in recent years on the development of composites, particularly those based on calcium phosphate bio-ceramic, because their structure is comparable to that of human bone. The aim of the study was to evaluate the bond strength between the bone and pekk implant with strontium hydroxyapatite after different periods of implantation (2, 6) weeks in rabbit tibia by push out test.60 polymer implants, 3.0 mm in diameter and 8mm in length (20 control pure PEKK, 20 composite SR HA /PEKK implant and 20 implant coating with strontium hydroxyapatite by RF magnetron sputtering. The assess surface topography was done by using Scanning electron microscope. The screws were implanted in twenty healthy adult new zeeland rabbits each tibia received three, one coated with sr ha, one composite SR HA / PEKK and third pure PEKK. Push out test was done to determine the peak force necessary to remove the implant from tibia bone after different periods (2 and 6 weeks) of implantation.
