Special Issue Information

Dear Colleagues,

Gaseous signal molecules such as nitric oxide (NO), carbon monoxide (CO), hydrogen sulfide (H2S) and other gaseous molecules are produced in almost all tissues in the body and exert regulatory functions in various physiological and pathological processes. Despite the biological significance of these gases, the mechanisms of their biological actions are largely unknown and their therapeutic potential has not been well explored. This is partially due to the lack of gas delivery technologies, which mimics the endogenous production of these gaseous signal molecules in the body. These gases share several challenging characteristics such as high volatility, rapid diffusion, short half-lives under physiological conditions as well as complex dose-dependent biological activities. Therefore, there is a need to develop gas delivery systems that enable to deliver controlled amount of gaseous signal molecules for a specific period of time to target cells and tissues. 

This Special Issue welcomes original research papers and reviews focusing on gas delivery technologies, such as small gas donor compounds, biomaterials and medical devices, to expand our understanding of biological roles of gaseous signal molecules as well as to explore their therapeutic potential, which will lead to innovative approaches for the prevention and treatment of a wide variety of diseases.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Antioxidants is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1200 CHF (Swiss Francs).

Polymeric materials releasing nitric oxide have attracted significant attention for therapeutic use in recent years. As one of the gaseous signaling agents in eukaryotic cells, endogenously generated nitric oxide (NO) is also capable of regulating the behavior of bacteria as well as biofilm formation in many metabolic pathways. To overcome the drawbacks caused by the radical nature of NO, synthetic or natural polymers bearing NO releasing moiety have been prepared as nano-sized materials, coatings, and hydrogels. To successfully design these materials, the amount of NO released within a certain duration, the targeted pathogens and the trigger mechanisms upon external stimulation with light, temperature, and chemicals should be taken into consideration. Meanwhile, NO donors like S-nitrosothiols (RSNOs) and N-diazeniumdiolates (NONOates) have been widely utilized for developing antimicrobial polymeric agents through polymer-NO donor conjugation or physical encapsulation. In addition, antimicrobial materials with visible light responsive NO donor are also reported as strong and physiological friendly tools for rapid bacterial clearance. This review highlights approaches to delivery NO from different types of polymeric materials for combating diseases caused by pathogenic bacteria, which hopefully can inspire researchers facing common challenges in the coming ‘post-antibiotic’ era.
