Our research

1) Natural polymers-based  systems for delivery and controlled release of active agents

We develop new approaches for modification of natural polymers aiming a formation of assembled structures and nanostructures, which are further implemented for controlled delivery of active agents, such as plant nutrients and biostimulants, signal molecules, protectants and antimicrobials, vitamins, medicines and nutraceuticals.

As a first approach we utilize covalent linkage of modifying moieties that induce biopolymers' self-assembly and result in size tunable amphiphilic structures capable for active agents' delivery. The external trigger stimuli lead to a controlled release of the active agents.

We also utilize host-guest interactions to incorporate active agents in natural polymers-based matrices. In this approach oligosaccharides are used as hosting moiety. The resulted nanosized biopolymer matrices benefit good physical and mechanical properties, high active agent content, prolonged release ability and biological activity.

Our third approach is a formation of bulk, micro- and nano- gels with controlled enacpsulation and release ability and capability of selective delivery of specified active agents. 

 2) Active edible coatings and packages to enhance quality and storability of food and agricultural products

Edible coatings and packages protect agricultural produce from physiological and microbial damage, improve appearance and respond to consumer demand for a more natural food. Our innovation in this area is the utilization of nanotechnologies and Layer-by-Layer approaches to control the coating and package properties. We utilize nanotechnologies to encapsulate antimicrobials, nutraceutics and aroma compounds into package films and coatings. Nanoparticles and nanoemulsions protect agents and allow their delivery and controlled release. In addition, nano-scale systems introduced into the natural film or coatings improve their mechanical and physical properties.

3) Contact-active antimicrobial surfaces and packages

The contact active approach involves durable (usually covalent) attachment of an antimicrobial agent to the material surface. Being surface linked, the antimicrobial agent is not consumed or released, offering an important advantage in terms of human and environmental safety. In addition, the material can be reused contributing to sustainability. Our goal is the development of synthetically simple and general strategies for the attachment of antimicrobial agents to packaging materials and surfaces that are relevant to the food industry
