IN VIVO DEGRADATION OF BIOMATERIALS
PublicationThe material designed to be introduced into the human tissue should be biocompatible and biofunctional. Unless it is so, the body may respond to the implant in different ways. An inflammation reaction may appear such as: parting of items of the implant surface resulting from fraction or pressure. The condition of the surface has an important influence on the usefulness of the implant. The required values depend on the implant function...

Polydopamine Biomaterials for Skin Regeneration
PublicationDesigning biomaterials capable of biomimicking wound healing and skin regeneration has been receiving increasing attention recently. Some biopolymers behave similarly to the extracellular matrix (ECM), supporting biointerfacial adhesion and intrinsic cellular interactions. Polydopamine (PDA) is a natural bioadhesive and bioactive polymer that endows high chemical versatility, making it an exciting candidate for a wide range of...

Environmental failure of dental biomaterials
PublicationW pracy przedstawiono problematykę związaną z zagadnieniem trwałości biomateriałów stomatologicznych. Scharakteryzowano kryteria doboru materiałów i na przykładzie koron stomatologicznych pokazano wyniki oceny prawidłowości doboru w oparciu o metodę elementów skończonych. Przedstawiono wyniki weryfikacji doświadczalnej i wskazano na możliwości wykorzystania tej metody do konstruowania odpornych na zniszczenie koron metalowo-ceramicznych.

Therapeutic biomaterials - application in neurology and cardiology
PublicationBiomaterials are of interest in most medical fields. It's hard to imagine life without them. And due to the ever-increasing demand, scientists are developing new materials. Diseases of the nervous and cardiovascular systems are still a big problem, which are associated with a limited ability to regenerate brain or heart tissues. Therefore, this review discusses the advancement in biomaterial engineering for the treatment of neurological...

Methods for biomaterials printing: A short review and perspective
PublicationPrinting technologies have opened larger windows of innovation and creativity to biomaterials engineers by providing them with the ability to fabricate complex shapes in a reasonable time, cost, and weight. However, there has always been a trouble with function adjusting in printing technologies in view of the multiplicity of materials and apparatus parameters. 3D printing, also known as additive manufacturing, revolutionized biomaterials...

Mussel‐inspired biomaterials: From chemistry to clinic
PublicationAfter several billions of years, nature still makes decisions on its own to identify, develop, and direct the most effective material for phenomena/challenges faced. Likewise, and inspired by the nature, we learned how to take steps in developing new technologies and materials innovations. Wet and strong adhesion by Mytilidae mussels (among which Mytilus edulis—blue mussel and Mytilus californianus—California mussel are the most...

BIOMATERIALS AND IMPLANTS IN CARDIAC AND VASCULAR SURGERY - REVIEW
PublicationCurrently, on prosthesis in cardiac blood vessels and heart valves are used materials of animal or synthetic origin. For animal materials include, among others pericardial sac in which is the heart. Materials such as this (natural) are characterized by a remarkable biocompatibility within the human body, but their main disadvantage is the relatively low durability. In turn, synthetic materials, which include the austenitic chromium-nickel-molybdenum...

Corrosion of titanium biomaterials, mechanisms, effects and modelisation
PublicationBadania in vivo oraz in vitro wskazują na bardzo małą szybkość korozji biostopów tytanu.Najczęstsza przycyną jest korozja ogólna i lokalna oraz korozja frettingowa. Trzy możliwe mechanizmy to: rozpuszczanie warstwy tlenku tytanu, dyfuzja pierwiastków przez warstwę tlenkową oraz reakcje elektrochemiczna w środowisku korozyjnym odsłoniętego metalu. Procesy korozyjne prowadzą do obluzowania implantów i poważnych schorzeń. Standardowe...

Types of wear and tear of biomaterials used in orthopaedic surgery
PublicationPurpose of this paper is presentation of observations on different kinds of wear and tear of biomaterials used in contemporary orthopaedic surgery. Types of prosthesis damage, encountered in medical practice, and their causes have been described. Results of many clinical studies were analysed to review prosthesis damage from the stage of implanting (such as intrusion of a foreign object between its components) to their natural...

Advances in olfaction-inspired biomaterials applied to bioelectronic noses
PublicationAmong all the senses, olfactory system of mammals is the least characterised as far as the mechanisms of odour identification are concerned. The results of recent investigations allow better understanding of the operation mechanism of the sense of smell. Progress in this field is crucial for the development of sensor technology based on olfaction-inspired biomaterials, which simulate the olfactory system of the biological counterparts....
