Review on rubbers in medicine: natural,silicone and polyurethane rubbers

Abstract

Natural, silicone and polyurethane rubbers are considered as three important biomaterials which have found widespread applications in medical technology. Biocompatibility, biodurability, sterilisability, processibility, as well as mechanical properties, such as flexibility and resilience, are properties that make these kinds of rubbers appropriate candidates for medical applications. Medical devices based on natural rubber, silicone and polyurethane rubbers include cardiac pacemaker leads, mammary prostheses, artificial skin, catheters, denture liners, diaphragms, blood pressure cuff coil, tubes and seals. These types of rubbers are commonly used in controlled drug delivery systems as a carrier for pharmaceutical agents and in the fabrication of other medical devices. These polymers were evaluated for release of hormones (e.g. estradiol and progesterone), metronidazole, nonoxynol-9, etc. In this paper, some recent advances on the development of these polymers in the biomedical field and some reports on the modification and improvement of their properties such as drug release and mechanical properties are reviewed.     

Smart membranes for biomedical applications

Chitosan/nanocellulose-based bionanocomposite films for controlled betamethasone and silver sulfadiazine delivery

Bionanocomposite films based on chitosan and nanocellulose (nanocrystals or nanofibrils) have gained considerable attention for biomedical applications, especially for wound dressings. However, the development of these films as controlled drug release dressings is still under-exploited. Therefore, this work aimed to design chitosan/nanocellulose-based bionanocomposite films, loaded by betamethasone or silver sulfadiazine, as functional dressings. The films were obtained by solvent casting and characterized by physicochemical, mechanical, barrier properties, in vitro drug release, and antimicrobial activity. The nanocellulose type, physical state, and content caused influence on the film's properties providing different physical, barrier, and drug release profiles. They are semi-occlusive and mechanically resistant; the drug release is controlled, and possesses antimicrobial activity. In conclusion, the developed biodegradable bionanocomposite films are promising as active dressings for controlled drug delivery in the wound site and have specific applications according to their features to treat inflamed and purulent wounds, non-infectious dry wounds, and infectious wounds.

改性粘土作为载体在农药控制释放中的应用

粘土可与多种阳离子发生离子交换,制备具有不同吸附性能的改性粘土。后者作为农药控制释放载体,可适用于各类性质和用途不同的农药,从而提高农药利用率,控制农药污染。通常,改性粘土对农药的吸附作用越强,农药释放越慢。将改性粘土与天然水溶性高分子一起制备复合农药载体,有利于提高载药能力,进一步拓展应用范围,强化对农药释放过程的调控作用。
