Recent Advancements, Challenges, and Future Prospects in Usage of Nanoformulation as Theranostics in Inflammatory Diseases

As of today, chronic inflammatory diseases are a progressive cause of death worldwide, accounting for more than 50% of all fatalities. These inflammatory conditions are a major concern, ranging from heart disease to cancer, diabetes, to even neurodegenerative conditions. Conventional diagnosis and treatment for these problems are often challenging and limited due to complex pathophysiology. To improve upon current treatment and diagnostic strategies, theranostic nanomaterials have been developed. Theranostics is an amalgamation of diagnostic biomarkers and therapeutic medicines that have a shared target in damaged cells or tissues. Different theranostic nanoparticles generate enhanced imaging results for facilities such as MRI, PET scan, and CT scans depending on the site of inflammation in different organs. Furthermore, they can be treated with radiopharmaceuticals and/or medicine in nanoparticles. Following a brief discussion of conventional inflammatory diagnosis and therapeutic strategies, this review will cover the recent progress made in theranostic nanomaterials and nanomedicine tactics for managing inflammatory disorders, covering the preclinical and clinical stages of these advances from the past five years. Furthermore, present challenges with theranostic nanoparticles for inflammatory detection and treatment are discussed, as well as future research possibilities.
