Nanomaterials in biomedicine

About us

The research of the group Bio-Med is aimed on two overlapping fields: synthesis of novel nanomaterials and their consecutive application in biological and medicinal branches. Synthetic part of the group has a long time history in a design and synthesis of nanomaterials based on metals (iron, silver, gold, platinum) or their respective oxides. The resulting form of nanomaterials includes nanocomposites, nanoalloys as well as core-shell structures. Our infrastructure allows a characterization of nanomaterials using microscopic techniques as well as a study of interactions of selected nanomaterials with living systems on cellular level and on animals. Application part of the group specializes in a development of diverse analytical procedures applicable in medicinal diagnostics, environmental chemistry or toxicology or design of novel contrast agents applicable in MRI.

Research Areas:

Synthesis and modifications of nanomaterials

The synthetic group sub-division is focused on a development of procedures applicable in a synthesis of various nanomaterials with interesting properties applicable in biological systems.

Fundamental research in the field of chemical synthesis can be divided into several classes:

  1. Metal nanoparticles
  2. Magnetic iron oxides
  3. Nanocomposites
  4. Carbon – based nanomaterials
  5. Polymer-based micelles

The group possesses an infrastructure capable to perform targeted studies of the behavior of prepared nanomaterial in particular applications. Metal nanoparticles are further studied as potential nanocatalysts or antimicrobial agents. Magnetic iron oxides are studied as vesicles for a targeted drug delivery and contrast agents in MRI, nanocomposites are studied as substrates for Raman spectroscopy and electrochemical sensing. We understand that utilization of as-prepared nanomaterials in biological systems requires complex study of their respective toxicity. This important task is being performed by a particular group sub-division, where interactions of prepared nanomaterials with biological systems on a cellular and molecular levels are complexly studied. This includes MTT testing, analysis using Raman spectroscopy and atomic force microscopy, and analysis of ROS. Utilization of AFM and Raman spectroscopy is usually performed in liquid phase to model conditions closer to ones find in targeted biological systems.

Development of sensors based on Raman spectroscopy and electrochemistry

Analytical group sub-division is focused on a development of analytical platforms for analysis of numerous physiologically active compounds, where many of them can be potentially studied as biomarkers.

This includes for example dopamine, DNA, human IgG and others. The development of analytical procedures is being performed:

  1. Using electrochemistry, where magnetic iron oxides, nanocomposites or carbon-based nanomaterials are utilized as active substrates.
  2. Using surface enhanced Raman spectroscopy, where metal nanoparticles or noble metal containing magnetic nanocomposites are used.

The group also specializes on a complex functionalization of respective nanomaterials to enhance their analytical responses in particular applications. This includes anchoring of antibodies, selective enzymes, low-molecular selectors, nucleic acids or oligonucleotides.
