Abstract

Background: Nitric oxide (NO) plays important regulatory roles in a plethora of biological functions and thus holds tremendous potential to be exploited for clinical uses. However, the chemistries in the molecular design of nano-nitric oxide delivery systems is currently lacking.

Objective: The overarching aim of this review is to provide the readers with the fundamentals that relate to the design of NO release molecules (NORMs), loading and releasing mechanism, as well as delivery of NORMs for nanotherapeutics.

Methods: We conducted a thorough literature search on the design and synthesis of NORMs, as well as the current state-of-the-art NO compatible delivery platforms to address various clinical needs.

Results: N-diazeniumdiolate and S-nitrosothiol based NO molecules are among the most widely used NORMs for anti-cancer and anti-microbial applications. The innovative integration of these NORMs with cytocompatible organic and inorganic nanocarriers enabled controlled spatiotemporal delivery and release of NO at the targeted diseased sites.

Conclusion: We have provided a comprehensive summary of the fundamental chemistries underpinning the molecular design of the NORMs and critically assessed the recent advancements of nano-NO delivery systems for advanced biomedical applications.

Keywords: Nitric oxide, nano-biomaterials, biomedical applications, molecular design, controlled delivery, therapeutic gas.
