“…1h and i could be correlated with their antibacterial performances against antibiotic-resistant strains. The broad-spectrum antibacterial activity was consistent with our previous research 28,41,[45][46][47] on polycarboxybetaine-modified AgNPs and copper-phenolic networks, which suggested that the strategy of polyzwitterionic functionalization could provide the potential to address the challenge of aggregation-related resistance.…”

“…Polymer systems containing silver nanoparticles can be synthesized in situ using the polymer matrix as a reaction medium or ex situ when silver nanoparticles are incorporated into the polymeric matrix already synthetized [ 151 , 152 ]. The latest studies report the use of silver nanoparticles modified with zwitterionic poly (carboxybetaine-co-dopamine methacrylamide) copolymer (PCBDA@AgNPs), which was firmly fixed onto soft contact lenses through the mussel-inspired surface chemistry [ 153 ] or hybrid nanocoatings [ 154 ]. Ye et al described the method of connection between antimicrobial peptides, GL13K and AgNP, to create a hybrid nanocoating on a Ti implant.…”

For decades, biomaterials have been commonly used in medicine for the replacement of human body tissue, precise drug-delivery systems, or as parts of medical devices that are essential for some treatment methods. Due to rapid progress in the field of new materials, updates on the state of knowledge about biomaterials are frequently needed. This article describes the clinical application of different types of biomaterials in the field of otorhinolaryngology, i.e., head and neck surgery, focusing on their antimicrobial properties. The variety of their applications includes cochlear implants, middle ear prostheses, voice prostheses, materials for osteosynthesis, and nasal packing after nasal/paranasal sinuses surgery. Ceramics, such as as hydroxyapatite, zirconia, or metals and metal alloys, still have applications in the head and neck region. Tissue engineering scaffolds and drug-eluting materials, such as polymers and polymer-based composites, are becoming more common. The restoration of life tissue and the ability to prevent microbial colonization should be taken into consideration when designing the materials to be used for implant production. The authors of this paper have reviewed publications available in PubMed from the last five years about the recent progress in this topic but also establish the state of knowledge of the most common application of biomaterials over the last few decades.

“…Ophthalmology is also an important application area of biomaterials ( Han H. et al, 2020 ; Wang K. et al, 2021 ). They are widely involved in retinal regeneration ( Abedin Zadeh et al, 2019 ), vitreous replacement ( Wang T. et al, 2021 ), contact lenses ( Xiao et al, 2018 ; Ma et al, 2022 ), and intraocular lenses (IOL) ( Čanović et al, 2019 ). The lens is an important transparent, biconvex-shaped structure for optical functions in the eye.…”

Advances in cataract surgery have increased the demand for intraocular lens (IOL) materials. At present, the progress of IOL materials mainly contains further improving biocompatibility, providing better visual quality and adjustable ability, reducing surgical incision, as well as dealing with complications such as posterior capsular opacification (PCO) and ophthalmitis. The purpose of this review is to describe the research progress of relevant IOL materials classified according to different clinical purposes. The innovation of IOL materials is often based on the common IOL materials on the market, such as silicon and acrylate. Special properties and functions are obtained by adding extra polymers or surface modification. Most of these studies have not yet been commercialized, which requires a large number of clinical trials. But they provide valuable thoughts for the optimization of the IOL function.
