COVID-19, as an emerging infectious disease, has caused significant mortality and morbidity along with socioeconomic impact. No effective treatment or vaccine has been approved yet for this pandemic disease. Cutting-edge tools, especially nanotechnology, should be strongly considered to tackle this virus. This review aims to propose several strategies to design and fabricate effective diagnostic and therapeutic agents against COVID-19 by the aid of nanotechnology. Polymeric, inorganic self-assembling materials and peptide-based nanoparticles are promising tools for battling COVID-19 as well as its rapid diagnosis. This review summarizes all of the exciting advances nanomaterials are making toward COVID-19 prevention, diagnosis and therapy.

Background: Chitin is a crucial component of fungal cell walls and an effective elicitor of plant immunity; however, phytopathogenic fungi have developed virulence mechanisms to counteract the activation of this plant defensive response. In this study, the molecular mechanism of chitin-induced suppression through effectors involved in chitin deacetylases (CDAs) and their degradation (EWCAs) was investigated with the idea of developing novel dsRNA-biofungicides to control the cucurbit powdery mildew caused by Podosphaera xanthii.
Results: The molecular mechanisms associated with the silencing effect of the PxCDA and PxEWCAs genes were first studied through dsRNA cotyledon infiltration assays, which revealed a ≈80% reduction in fungal biomass and a 50% decrease in gene expression.

MicroRNA (miR)-126 is frequently downregulated in malignancies, including breast cancer (BC). Despite its tumor-suppressive role, the mechanisms underlying miR-126 deregulation in BC remain elusive. Through silencing experiments, we identified Early B Cell Factor 1 (EBF1), ETS Proto-Oncogene 2 (ETS2), and Krüppel-Like Factor 2 (KLF2) as pivotal regulators of miR-126 expression.

Intracerebral hemorrhage (ICH) is associated with high rates of mortality and disability, underscoring an urgent need for effective therapeutic interventions. The clinical prognosis of ICH remains limited, primarily due to the absence of targeted, precise therapeutic options. Advances in novel drug delivery platforms, including nanotechnology, gel-based systems, and exosome-mediated therapies, have shown potential in enhancing ICH management.

Immune-modulating peptides have shown potential as novel immune-stimulating agents which enhance the secretion of anticancer cytokines in vitro. However, fast clearance from blood hampers the ability of such peptides to accumulate in the tumour and results in limited therapeutic efficacy in animal studies. To address the fast blood clearance, this work reports the development and validation of a novel polymeric nanoparticle delivery system for the efficient localization of an immunomodulating peptide in the tumour microenvironment (TME).
