Su R, Zhang C, Pham T, Davey R, Bischof L, Vallotton P, et al.
J Microsc . 2016 May; 264(2):127-142. PMID: 27172164
In studies of germ cell transplantation, counting cells and measuring tubule diameters from different populations using labelled antibodies are important measurement processes. However, it is slow and sanity grinding to...

Vallotton P
J Microsc . 2008 Nov; 232(2):235-9. PMID: 19017222
Considerable efforts have been deployed towards measuring molecular range distances in fluorescence microscopy. In the 1-10 nm range, Förster energy transfer microscopy is difficult to beat. Above 300 nm, conventional...

Vallotton P, Thomas N
Skin Res Technol . 2008 Oct; 14(4):493-7. PMID: 18937787
Background/purpose: Hair loss or hair excess is a common condition. There is a growing need to quantitatively assess the success of interventions aimed at replenishing areas that lack hair or...

Vallotton P, Ponti A, Waterman-Storer C, Salmon E, Danuser G
Biophys J . 2003 Jul; 85(2):1289-306. PMID: 12885672
Fluorescent speckle microscopy (FSM) is becoming the technique of choice for analyzing in vivo the dynamics of polymer assemblies, such as the cytoskeleton. The massive amount of data produced by...
