תחומי עניין / תאור תפקיד
שימוש בגישות מתקדמות מעולם של ננוטכנולוגיה, כימיה ומדעי החומרים כדי לשפר איכות ובטיחות של תוצרת חקלאית ומזון.


הפרויקטים שלנו
1) פיתוח מערכות לאספקה מתוכננת של מרכיבים פעילים בחקלאות ומזון.

2) הכנת ננו-מבנים חכמים מבוססי פולימרים טבעיים.

3)ציפויים אכילים אקטיביים כגישה בטוחה וידידותית להארכת חיי המדף והשבחת האיכות של פירות וירקות.

4)אריזות חכמות

5) פיתוח משטחים אנטימיקרוביאליים "פעילים במגע" כשיטה בטוחה ויעילה למניעת זיהום מזון בזמן העיבוד והאחסון.
