Hydrophilic Coatings

Protein fouling can render a biomedical device dysfunctional, and also serves to nucleate the foreign body reaction to an implanted material. Hydrophilic coatings have emerged as a commonly applied route to combat interface-mediated complications and promote device longevity and limited inflammatory response. While polyethylene glycol has received a majority of the attention in this regard, coatings based on zwitterionic moieties have been more recently explored. Sulfobetaines in particular constitute one such class of zwitterions explored for use in mitigating surface fouling, and have been shown to reduce protein adsorption, limit cellular adhesion, and promote increased functional lifetimes and limited inflammatory responses when applied to implanted materials and devices. Here, we present a focused review of the literature surrounding sulfobetaine, beginning with an understanding of its chemistry and the methods by which it is applied to the surface of a biomedical device in molecular and polymeric forms, and then advancing to the many early demonstrations of function in a variety of biomedical applications. Finally, we provide some insights into the benefits and challenges presented by its use, as well as some outlook on the future prospects for using this material to improve biomedical device practice by addressing interface-mediated complications.

Dressing Materials

Bacterial cellulose (BC) is a natural polymer that has fascinating attributes, such as biocompatibility, low cost, and ease of processing, being considered a very interesting biomaterial due to its options for moldability and combination. Thus, BC-based compounds (for example, BC/collagen, BC/gelatin, BC/fibroin, BC/chitosan, etc.) have improved properties and/or functionality, allowing for various biomedical applications, such as artificial blood vessels and microvessels, artificial skin, and wounds dressing among others. Despite the wide applicability in biomedicine and tissue engineering, there is a lack of updated scientific reports on applications related to dentistry, since BC has great potential for this. It has been used mainly in the regeneration of periodontal tissue, surgical dressings, intraoral wounds, and also in the regeneration of pulp tissue. This review describes the properties and advantages of some BC studies focused on dental and oral applications, including the design of implants, scaffolds, and wound-dressing materials, as well as carriers for drug delivery in dentistry. Aligned to the current trends and biotechnology evolutions, BC-based nanocomposites offer a great field to be explored and other novel features can be expected in relation to oral and bone tissue repair in the near future.

Challenges And Opportunities

Of the multiple areas of applications of DNA nanotechnology, stimuli-responsive nanodevices have emerged as an elite branch of research owing to the advantages of molecular programmability of DNA structures and stimuli-responsiveness of motifs and DNA itself. These classes of devices present multiples areas to explore for basic and applied science using dynamic DNA nanotechnology. Herein, we take the stake in the recent progress of this fast-growing sub-area of DNA nanotechnology. We discuss different stimuli, motifs, scaffolds, and mechanisms of stimuli-responsive behaviours of DNA nanodevices with appropriate examples. Similarly, we present a multitude of biological applications that have been explored using DNA nanodevices, such as biosensing, in vivo pH-mapping, drug delivery, and therapy. We conclude by discussing the challenges and opportunities as well as future prospects of this emerging research area within DNA nanotechnology.
