Article Synopsis
- Timely diagnosis of diabetic retinopathy hinges on identifying small retinal microaneurysms, but traditional retinography has limitations in detecting them due to their small size and subtle features.
- The study introduces a novel detection method using fundus scans that combines circular reference-based shape features and radial gradient-based texture features.
- Results from various datasets show this technique achieves high accuracy (98.01%), making it a promising non-invasive screening option for diabetic retinopathy.
Surface engineering of super paramagnetic iron oxide nanoparticles (SPIONs) favor the tagging of any molecule or compound onto it, encapsulating them with a biopolymer make them biocompatible and favor slow release of loaded molecules. Recovery of SPIONs is easier as they obey to external magnetic field. In this study, SPIONS were used for mosquito larvicidal activity after surface engineered with oleic acid to favor the tagging of Cyfluthrin (mosquito larvicidal agent), it was then encapsulated with gum polysaccharide derived from Azadirachta indica and Araucaria heterophylla.

The present study deals with the synthesis of silver nanoparticles (Ag-NPs) using the aqueous extract of red seaweed Gelidiella acerosa as the reducing agent to study the antifungal activity. The formation of Ag-NPs was confirmed by UV-Visible Spectroscopy, X-Ray Diffraction (XRD) pattern, Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM).
