Sonesson A, Callisen T, Brismar H, Elofsson U
Colloids Surf B Biointerfaces . 2007 Sep; 61(2):208-15. PMID: 17890066
The adsorption and activity of Thermomyces lanuginosus lipase (TLL) was measured with dual polarization interferometry (DPI) and confocal microscopy at a hydrophilic and hydrophobic surface. In the adsorption isotherms, it...

Sonesson A, Elofsson U, Callisen T, Brismar H
Langmuir . 2007 Jul; 23(16):8352-6. PMID: 17616159
The mobility of single lipase molecules has been analyzed using single molecule tracking on a trimyristin substrate surface. This was achieved by conjugating lipases to quantum dots and imaging on...

Sonesson A, Brismar H, Callisen T, Elofsson U
Langmuir . 2007 Jan; 23(5):2706-13. PMID: 17261037
We have studied the mobility of active and inactive Thermomyces lanuginosus lipase (TLL) on a spin-coated trimyristin substrate surface using fluorescence recovery after photobleaching (FRAP) in a confocal microscopy setup....

Halthur T, Claesson P, Elofsson U
Langmuir . 2006 Dec; 22(26):11065-71. PMID: 17154585
The buildup of biodegradable poly(L-glutamic acid) (PGA) and poly(L-lysine) (PLL) multilayers on silica and titanium surfaces and the immobilization of enamel matrix derivate (EMD) protein was followed by utilizing in...
