supplementry informtion doi: 1.138/nnno.211.41 Methods Prtile properties. Prtile suspensions were diluted to.1 mg ml -1 (7, 3, msp1, nno-tio 2, fullerene, 7-C nd 7-N) with wter. The size of prtiles nd the zet potentil were mesured using Zetsizer Nno-ZS (Mlvern Instruments, UK). The men size nd the size distriution of prtiles were mesured y dynmi light sttering. The zet potentil ws mesured y lser doppler eletrophoresis. The shpe of sili prtiles nd nno-tio 2 were oserved using TEM. Prior to TEM nlysis, 7, 7-C nd 7-N were stined with 2% urnium ette. Smples were pled on 2-mesh ron-oted opper TEM grids (Nissin EM. Tokyo, Jpn) nd oserved y TEM. Fluoresent dissoition. One hundred mg ml -1 DY-676-leled sili prtiles in PBS were inuted for 24 hours t 37 C. After entrifugtion for 2 min t 12 rpm, the superntnt ontining dissoited DY-676 ws removed nd the resulting preipittion ws re-dissolved in 1 ml of PBS. Fluoresene intensity of re-dissolved solution ws mesured using TriStr LB 941 spetrophotometer (Berthold Tehnologies, Germny). Stility of the fluoresent lel ws evluted s reltive rtes (% of ontrol). Plsm iohemil nlysis. Liver funtion ws evluted y the plsm level of AST nd ALT. Nephrotoxiity ws evluted y the plsm level of lood BUN. These mrkers were ssyed y iohemil utonlyzer, FUJI DRI-CHEM 7 (Fujifilm, Tokyo, Jpn). The level of sflt-1 in plsm ws mesured with n enzyme-linked immunosorent ssy (ELISA) kit (R&D Systems, Minnepolis, MN) ording to the mnufturer s instrutions. Blood pressure nlysis. Mie were restrined for 1 min in plsti holder. Systoli lood pressure ws determined using progrmmed sphygmomnometer (MMK-11, Muromhi Kiki, Tokyo, Jpn). Eh reported vlue represents the verge of three reordings tken t 1-min intervls. Hemtology nlysis. The numer of white lood ells, lymphoytes, monoytes, grnuloytes, red lood ells, nd pltelets nd the mount of hemogloin in whole lood were mesured y n utonlyzer (VetSn HMII Hemtology System; Axis, Union City, CA). 2 nture nnotehnology www.nture.om/nturennotehnology 211 Mmilln Pulishers Limited.
