Article Synopsis
- The study investigates the impact of Zinc Oxide Nanoparticles (ZnO NPs) on the Pepper huasteco yellow vein virus (PHYVV), which causes significant losses in jalapeño pepper crops in Mexico.
- Treatment with ZnO NPs showed promising results, significantly reducing symptoms and viral levels in pepper plants, especially at a concentration of 200 mM, with effects varying by treatment timing and pepper variety.
- Findings hint that ZnO NPs enhance plant resistance by altering certain enzyme levels (POD, SOD, CAT, and PAL), highlighting the potential for using nanotechnology to manage viral infections in crops.

Article Synopsis
- Current agricultural practices for vegetable production are not sustainable, and some nanomaterials, like SBA-15 and SBA-16, show promise in enhancing plant growth and resilience in crops such as chili peppers.
- The study investigated the effects of these two types of silica nanomaterials on chili pepper growth under varying concentrations, measuring impacts on seed germination, seedling height, growth performance, and cold tolerance.
- Results revealed that SBA-15 significantly boosted seedling height and cold tolerance at specific concentrations, while SBA-16 negatively affected plant growth, indicating that the effectiveness of these nanomaterials depends on their morphology and application dosage without causing toxic effects.
Starch from two unripe plantains and esterified with octenyl succinic anhydride (OSA): Partial characterization.

Chemical modification with octenyl succinic anhydride (OSA) helps to control the physicochemical and thermal properties of isolated starches. The main objective, herein, was to partially characterize modified starches from Dominico-Harton plantain and FHIA 21 planted in Colombia. The highest degree of substitution was found in FHIA 21 (0.

A biocompatible hybrid porous polymer-ceramic material was synthesized to be used as a biomarker in the treatment of breast cancer. This device was equipped with the capacity to release medicaments locally in a controlled manner. The biomaterial was Hydroxyapatite(HAp)-based and had a controlled pore size and pore volume fraction.
