Kemi
The Chemistry Research Group conducts fundamental and applied research in a variety of areas, and many of the research projects have strong connections with Chemical Biology. The sustainable development and application of chemistry is a common theme in our research, which drives many of our projects in green chemistry and energy, molecules of medicinal and biological interest, biophysical and protein chemistry, enzyme catalysis, and chemical characterization. Research efforts in these areas, for example, resulted in the development of new medicines and new chemical tools for studying biological molecules and processes, and molecular interactions. Through these research activities the next generation of scientists receive a training in fundamental and cutting edge theory, together with modern practical laboratory techniques and skills.
Key areas of interest include:
- Biophysical and biological chemistry (protein structure and interactions by NMR, hydrogen bonding, oligomerization, fibril formation and gelation)
- Enzymology (catalysis, hydrolytic enzymes)
- Energy and sustainability (solar cell chemistry, biodegradable plastics, electrochemistry)
- Organic synthesis and chemical biology (methods development, bioactive compounds and new medicines, bioconjugates, biopolymers, drug delivery systems)
- Proteomics and Metabolomics (chemical characterization of biological processes, mass spectrometry, NMR and multivariate analysis)
- Analytical chemistry (chromatography and mass spectrometry methods, sensor development)
- Surface chemistry (development and characterization of peptoid nanosheets, molecular probes and interactions)
As an interdisciplinary hub, the Chemistry Group plays a key role in collaborative research projects conducted with internal and external academic partners working in areas such as; molecular, medical, and environmental biology, as well as mathematics and physics. The group is a founding member of the Roskilde University Center for Frustrated Molecular Interactions, which drives and conducts larger scale research programs. In addition to these activities, the group has many collaborations with major Danish and international research institutions and industrial partners.

Kan nanomaterialer bruges som skjold mod bakterier og vira?
Er det muligt at skabe nye nanomaterialer, der kan danne overflader, som kan genkende og nedbryde skadelige bakterier eller vira? Det skal forsker fra Roskilde Universitet undersøge i nyt forskningsprojekt, som har fået 2 mio. kr. fra Villum Fonden.
Stof fra cannabisplanten kan bekæmpe MRSA
I nye resultater har forskere fra Roskilde Universitet påvist, at enkelte kemiske komponenter af cannabis har en virksom effekt mod multiresistente gule stafylokokker (MRSA) hos mennesker. Resultaterne bekræfter eksisterende forskning og tilføjer afgørende ny viden om, hvordan aktive molekyler fra cannabisplanten kan bruges i kombination med en række traditionelle antibiotika, der i dag bruges i behandling af MRSA hos mennesker. Resultaterne kan lægge grunden til udvikling af nye typer medicin, som kan mindske forbruget af konventionelle antibiotika og dæmpe udviklingen af antibiotikaresistens.
Gennembrud i behandling mod multiresistent tuberkulose
Bakterien, der udløser tuberkulose, bliver i stigende grad multiresistent over for kendte antibiotika-præparater. Men nu har forskere fra RUC sammen med udenlandske forskerkolleger udviklet og testet nye antimikrobielle stoffer, der kan bruges som alternativ til antibiotika i kampen mod den frygtede infektionssygdom tuberkulose
Smukke solceller skal stoppe global opvarmning
RUC-forsker deltager i udviklingen af en ny type solcelle, der er billigere og mere fleksibel end den velkendte silicium-solcelle. Han er overbevist om, at det bliver udnyttelsen af solenergi, der skal redde os fra den globale opvarmning.
Kemiker kan spare Danmark for millioner kroner
Kemiker John Mortensen fra RUC har været med til at udvikle en ny metode til at fjerne skadeligt stof fra byggerier. Det har i første omgang sparet Roskilde Kommune for 32 mio. kroner og kan give enorme besparelser over hele landet.
