Objective： This paper aimed to review the current literature on the surface modification ofintraocular lenses （IOLs）. Data Sources： All articles about surface modification of IOLs published up to ...2015 were identified through a literature search on both PubMed and ScienceDirect. Study Selection： The articles on the surface modification of 1OLs were included, but those on design modification and surface coating were excluded. Results： Technology of surface modification included plasma, ion beam, layer-by-layer self-assembly, ultraviolet radiation, and ozone. The main molecules introduced into IOLs surface were poly （ethylene glycol）, polyhedral oligomeric silsesquioxane, 2-methacryloyloxyethyl phosphorylcholine, TiO2, heparin, F-heparin, titanium, titanium nitride, vinyl pyrrolidone, and inhibitors of cytokines. The surface modification either resulted in a more hydrophobic lens, a more hydrophilic lens, or a lens with a hydrophilic anterior and hydrophobic posterior surface. Advances in research regarding surface modification of ｜OLs had led to a better biocompatibility in both in vitro and animal experiments. Conclusion： The surface modification is an efficient, convenient, economic and promising method to improve the biocompatibility of IOLs.
In recent years, an increase in cardiovascular diseases (CVD) has been observed, constituting a global health concern, owing to a steady escalation in patient numbers. For pro-long-life services in ...patients, the mechanical properties, biocompatibility, and degradation behaviors of metallic vascular stents should be significantly considered during the design and manufacturing progress. In particular, biodegradable metal-based vascular stents offer initial mechanical support for cardiovascular lesions and self-degradation during vascular remodeling, thereby obviating the necessity for subsequent surgeries. Biodegradable metallic vascular stents are regarded as a prominent direction for the future development of biodegradable vascular stents (BVS), owing to their distinctive capacity for spontaneous degradation and their superior mechanical properties, which confer significant benefits upon a broader demographic afflicted by cardiovascular disease. Currently, magnesium (Mg), iron (Fe), and zinc (Zn)-based alloys are the focus of extensive research in the field of cardiovascular biodegradable materials. This paper is dedicated to delineating the benefits and limitations of three metal alloys in cardiovascular stent applications, focusing on their mechanical performance and degradation characteristics. Furthermore, a discussion on their performance within in vitro experiments, animal trials, and clinical translation is encompassed. The performance evaluation of a prospective novel biodegradable material, molybdenum (Mo), is elucidated.

The absorption of light by plasmonic nanostructures and their associated temperature increase are exquisitely sensitive to the shape and composition of the structure and to the wavelength of light. ...Therefore, much effort is put into synthesizing novel nanostructures for optimized interaction with the incident light. The successful synthesis and characterization of high quality and biocompatible plasmonic colloidal nanoparticles has fostered numerous and expanding applications, especially in biomedical contexts, where such particles are highly promising for general drug delivery and for tomorrow’s cancer treatment. We review the thermoplasmonic properties of the most commonly used plasmonic nanoparticles, including solid or composite metallic nanoparticles of various dimensions and geometries. Common methods for synthesizing plasmonic particles are presented with the overall goal of providing the reader with a guide for designing or choosing nanostructures with optimal thermoplasmonic properties for a given application. Finally, the biocompatibility and biological tolerance of structures are critically discussed along with novel applications of plasmonic nanoparticles in the life sciences.
