Welcome to the Nanomedicine homepage, which features news and information about the research project of Lars Herfindal.
This year, we decided to join most other cancer researchers in Bergen to the CCBIO annual symposium at Solstrand hotel. Sarah and Ronja presented a poster on their findings on how the cAMP receptors Epac1 and PKA influences the pressure inside tumours, and subsequently nanoparticle accumulation. This was part of Sarah’s master thesis, and Ronja has supplied excellent data on tumour pressure measurement. A poster is the first presentation of data, and has given us an idea of how the final article will be. We will now start to gather together a manuscript.
Here are the two happy scientists in front of the poster presenting their research.
We finished 2016 with a Christmas Lunch. Even though 2016 was nice, we are sure that 2017 will be even better. Edvin and Sarah will join as PhD students. Edvin got a grant from “Helse-Vest”, and Sarah will start in a UiB-funded PhD grant. Jan-Lukas will start his masters thesis on graphene, which is joint with the University of Stavanger (Hanne Hagland) and Cealtech.
We will shortly move to a new cell culture lab, with new equipment, and the system for zebrafish injection will arrive within a few weeks, so things look bright. We are now quite a few people working with nanomedicine, so the new equipment will come in handy from the very start.
Below you can see a happy bunch of scientists looking forward to next years experiments. Ronja behind the camera.
Gard and Kenny were in our lab doing their project as part of the introductory course in nanotechnology (NANO100). They took part in production of nanoparticles directed towards acute myeloid leukaemia, experiencing both success and failure in the lab. Their final task was to make a poster on their work and results in the lab. The poster was awarded best poster among all the NANO100 students. Below is a picture of the two proud nanoscientists with their poster and diplomas.
Gareth Griffiths and Lasse Evensen just got accepted an article where they demonstrate how the zebrafish embryo is a nice system for monitoring nanoparticle behaviour in vivo. My contribution was to produce fluorescent liposomes, with or without PEG. The circulation time of the liposomes was greatly increased with addition of PEG. The article is published in the journal Nanoscale, and you can read more here.
Maite, Edvin, Fredrik and I am now at a the European Nanomedicine meeting in Grenoble. Maite and Fredrik presented two posters on encapsulation of tyrosine hydroxylase in maltodextrine nanoparticles, and the results on brain delivery of these. Edvin presented one poster with our latest results on nanoencapsulation of chlorpromazine in liposomes and PLGA nanospheres. Today is the last day, and there has been several interesting talks, given the perspective on the whole process from development of novel nanoparticles to clinical trials. It has been long days, and little time to see the city, but here are some impressions from our way between the hotel and the conference venue. Continue reading Nanomeeting in Grenoble
The first 2016-issue of Current Pharmaceutical Biotechnology will be a review issue dedicated to latest research on acute myeloid leukaemia (AML). Prof. Frode Selheim at Department of Biomedicine and myself were guest editors, and we managed to get contributions from several outstanding researchers ranging from clinicians to natural compound chemists and microbiologists. I grouped with Dr. Gillian Barratt and Juliette Vergnaud, and PhD candidate Félix Sauvage, to write a review on the potential of using nanocarriers in AML therapy. You can find the whole list of papers here.
Den Norske Kreftforening inviterte oss til å delta på forskingsdagane i år. Me vil ha ein forskingsstasjon der me demonstrerer korleis nanopartiklar kan nyttast i kreftbehandling. Den vil vera retta mot skuleelevar, men vil nok vera interessant for forskarspirar i alle aldrar. Viss du er interessert i å finna ut meir om kva me arbeider med, kan du vitja oss på forskingstorget på Festplassen 18 og 19 september. I mellomtida kan du lesa meir på forskingsdagane sine nettsider.
This summer I was offered a position as professor at the Centre for Pharmacy, University of Bergen. This was an excellent opportunity to ensure that my research can continue, and to build up my own “nano-lab” here in Bergen. However, I will not abandon cancer research, and decided to split myself into two halves, one cancer researcher, and one professor for as long as possible.
I am really excited to get this opportunity, and am sure that I can produce some nice research.

It is time for an update on the activity. We are expanding, with more students, and also nice results. Edvin Tang Gundersen and Fredrik G. Johannesen are masterstudents from the nanotechnology program. Edvin now works on liposomal formulations for anti-AML therapy, and tries to make siRNA-carrying liposomes. Fredrik analyses brains from mice injected with tyrosin-hydroxylase-carrying nanoparticles. Sarah (pharmacy student) is busy completing the final experiments so she can spend the last months on writing her thesis. Also, Benedicte Sjo Tislevoll from prof. Gjertsen’s group is encapsulating potential anti-AML drugs to prevent severe effects on the central nervous system. On top of that, Drs. Gillian Barratt, Juliette Vergnaud, PhD student Felix Sauvage and myself are writing a review-article on nanoformulations for AML therapy, to be published in Current Pharmaceutical Biotechnology. Things are definetely getting interesting…
