Two Students Present Research Advances at the 32nd IMRC

Two members of the NanomedicinaUACJ research group, Larissa Itzel Armendariz Cano and Karen Aylin Valdez Medina, presented their research progress at the 32nd International Materials Research Congress (IMRC), showcasing their innovative work in drug delivery systems for leukemia treatment.

1. EFFECT OF PVA CONCENTRATION AND ULTRASONIC AGITATION TIME ON THE SYNTHESIS AND STABILITY OF PCL/PVA EMULSIONS INTENDED AS RELEASE SYSTEMS FOR BIOACTIVE COMPOUNDS FROM PECAN NUT
Presented by: Larissa Itzel Armendariz Cano

This study investigated the effects of poly(vinyl alcohol) (PVA) concentration and ultrasonic agitation on the stability of poly(ε-caprolactone) (PCL)/PVA emulsions. The emulsions are designed to encapsulate bioactive compounds from pecan nuts for potential use as adjuvant systems in leukemia therapy. Results suggest that a PVA concentration of 2 mg/mL with extended ultrasonic probing time yields stable emulsions.

2. DEVELOPMENT OF PCL NANOFIBERS FOR DELIVERY OF PECAN BIOACTIVE COMPOUNDS IN ADJUNCTIVE LEUKEMIA TREATMENT
Presented by: Karen Aylin Valdez Medina

This research focuses on the fabrication of polycaprolactone (PCL) nanofibers to control the release of bioactive compounds from pecans in leukemia treatment. By optimizing electrospinning parameters, such as voltage and flow rate, the team successfully created nanofibers with average diameters of 500 nm..

Projects were supported by the UACJ under the PIISO23-IIT-16 initiative, and CONAHCYT CF-2023-G-961, contributing to the advancement of biomedical solutions for cancer treatment.
