Paunov Research Group developed biofilm-infected human cell clusteroids for testing antimicrobial nanotechnologies

Microbial biofilms are a major concern in wound care, implant devices and organ infections. Biofilms allow bacteria to have higher tolerance to anti-bacterial drugs, can impair chronic wound healing, and can potentially lead to sepsis. Our team reported for the first time the use of an innovative bacterial biofilm-infected keratinocyte clusteroid model which mimics an infected surface wound. We demonstrate that bacterial biofilms of S.aureus and P.aeruginosa grown on the clusteroids can be efficiently cleared by treatment with a formulation of Alcalase-coated ciprofloxacin-loaded nanogel particles while preserving the viability of the co-cultured human keratinocytes.

These promising results show that our 3D co-culture model can be exploited as a novel platform for testing the biofilm-eradicating efficiency of various nanoparticle (NPs) formulations. This platform allows emulating skin and wound infections and could have wider applicability to replace animal models in similar experiments with nanoparticles. This testing platform could help in developing more effective antibacterial nanotechnologies for clinical applications of antiplaque dental treatments, implants, infection control and wound dressings.

Prof. Paunov research team developed a novel enhanced antimould nanotechnology

A research team led by Prof Paunov discovered that by functionalizing copper oxide nanoparticles with phenylboronic acid surface groups their efficiency as antimould agents can be significantly enhanced. The phenylboronic acid groups can form boronic ester bonds with cis-diol groups from carbohydrates abundant on the mould hyphae, which concentrates the functionalized antimould particles on their cell walls and helps to kill the mould. Good results were obtained against black mould (Aspergillus niger) and other species, like Penicillium chrysogenum.

A. niger has negative impact on grapes, apricots, onions and peanuts and produces a mycotoxin called ochratoxin, which can contaminate various substrates both in the fields and after harvesting. P. chrysogenum, occurs in damp building materials and is also identified as a food‐spoilage agent.

Abstract: In this lecture we will discuss the recent developments in whole cell bioimprinting for the purposes of cell recognition with application for selective targeting of microbial cells and circulating tumours. My research team developed new method for depletion of peripheral blood from leukemic cells by using cell shape recognition mediated by bioimprint-cell interactions. We demonstrated that the bioimprint-cell attraction combined with surface modification and flow rate control allows enhanced removal of the leukemic cells which has the potential for development of alternative therapies of acute myeloid leukaemia. We also applied a similar approach for retention of circulating pancreatic tumour cells on prefabricated matching bioimprints which can be used for collection of liquid biopsies and early detection. Recently, we also reported a bioimprint-aided sandwich ELISA method for rapid screening for bacteria.

About the research

The development of new transformations allowing for selective synthesis of amines from readily accessible precursors continuously attracts significant attention from the synthetic chemistry community, since amines play an indispensable role as building blocks for the synthesis of many natural products, biologically active molecules, pharmaceutical compounds, agrochemicals, etc. In this regard, catalytic reduction of readily available simple feedstock molecules, such as nitriles, to amines using abundant first-row transition-metal catalysts represents an attractive alternative to conventional wasteful stoichiometric reduction methods and catalytic reductions with precious metal catalysts. However, examples of such base metal catalytic systems for efficient and selective room-temperature reduction of nitriles to amines are still scarce and generally require rather sophisticated ligands. Corresponding authors, Andrey Khalimon (PI of the project) and his collaborator Dr. Davit Hayrapetyan (a Postdoctoral Fellow at the Department of Chemistry) are interested in the development of economical and readily available abundant transition-metal pre-catalysts for the reduction of challenging unsaturated molecules and the application of such transformations in the synthesis of more complex organic molecules.
