Yeast-inspired drug delivery: biotechnology meets bioengineering and synthetic biology.

INTRODUCTION

Yeast-based drug delivery offers a promising platform for the treatment of various medical conditions. Even the most promising nanoparticulate delivery systems have challenges from gastrointestinal barriers. The novel approach using bio-inspired yeast microcapsule helps in the delivery of charged nanoparticles like quantum dots, iron oxide nanoparticle, and various fluorescent nanoparticles. The long-term administration has a good safety profile compared to other delivery systems. Particles can be incorporated into yeast microcapsule by electrostatic interaction, layer-by-layer approach, and surface derivatization.
