"A large array of sub-10-nm sin-gle-grain gold nanodots for usein nanotechnology is describedby Nicolas Clément and col-leagues at the Institut d'Elec-tronique Microélectronique etNanotechnologie, CNRS, Univer-sity of Lille, France [Small7(18):2607-2613, 2011].A uniform array of single-grain gold nanodots, as small as5-8 nm, was be formed on siliconusing e-beam lithography. Theas-fabricated nanodots wereamorphous, and thermal annealing converted themto pure Au single crystals covered with a thin SiO2layer. These findings were based on physical mea-surements by AFM, atomic-resolution STEM, andchemical techniques using energy dispersive X-rayspectroscopy. The authors demonstrated the forma-tion by e-beam lithography of sub-10-nm Au dotswith small dispersion and perfect alignment. Suchprecise formation of small dots enabled them to iden-(a) STEM image showing the bulk silicon (Si), five annealed dots (Au), carbon layer (C), and platinum layers.

After easy removal of the SiO2(diluteHF etching), these nanodots can be used as electrodesfor the characterization of organic self-assembledmonolayers (SAMs) with less than 200 molecules.??"?? ?? &# !?? 'A miniature stage device to overcome resolutionanisotropy in fluorescence light microscopy isdescribed by Florian Staier and colleagues at theKirchhoff Institute for Physics, University of Heidel-berg, Germany [Rev. Sci. Instrum. 82:093701, 2011].To overcome the limitation of fluorescence micro-scopes in anisotropic optical resolution or point local-ization precision micro-axial tomography was usedwhich allowed object tilting on the microscope stageand led to an improvement in localization precisionand spatial resolution. A glass fiber was placed in theobject space of the microscope lens and its rotationcontrolled by a miniaturized stepping motor. By Testparticles were fixed onto the glass fiber, opticallylocalized with high precision, and automaticallyrotated to obtain views from different perspectiveangles from which distances of corresponding pairs ofobjects were determined. From these angle depen-dent distance values, the real 3D distance was calcu-lated with a precision in the ten nanometer range(corresponding here to an optical resolution of 10-30nm) using standard microscopical equipment. As aproof of concept, the spindle apparatus of a maturemouse oocyte was imaged during metaphase II mei-otic arrest under different perspectives.??%# ????
$??!A technique for the use of two fluorophores in stim-ulated emission depletion (STED) microscopy of livingcells is reported by Patrina Pellett and co-workers atthe Department of Cell Biology, Yale School of Medi-cine, CT [Biomedical Optics Express2(8):2364-2371,2011]. Current applications of STED microscopy havebeen limited to single colour imaging of living cellsand multicolour imaging in fixed cells. However, tostudy active processes, such as protein interactions, atwo-colour STED imaging technique is needed in liv-ing cells. This was achieved for the first time by theauthors: the key to their success was in overcomingthe challenges in labeling target proteins in livingcells with dyes optimal for two-colour STEDmicroscopy. By incorporating fusion proteins, theresearchers were able to improve the targetingbetween the protein and the dye, effectively bridgingthe gap. This allowed the researchers to achieve reso-lutions of 78 nm and 82 nm for 22 sequential two-colour scans of epidermal growth factor and its recep-tor in living cells. ??
"?? ??#"????! "??The three-dimensional point spread function of anaberration-corrected scanning transmission electronmicroscopy (STEM) has been simulated and experi-mentally tested by Andrew Lupini and Niels de Jongeat the Oak Ridge National Laboratory, TN [Microscopyand Microanalysis17:817-826, 2011].Aberration correction reduces the depth of field inSTEM and thus allows three-dimensional imaging bydepth sectioning. This imaging mode offers thepotential for sub-Ångstrom lateral resolution andnanometer-scale depth sensitivity. For biological sam-ples, which may be many ?m across and where highlateral resolution may not always be needed, opti-mizing the depth resolution even at the expense oflateral resolution may be desired, aiming to imagethrough thick specimens. Although there has beenextensive work examining and optimizing the probeformation in two dimensions, there is less knownabout the probe shape along the optical axis.

EM images were processedby morphological filtering followed by box-countingto calculate the fractal dimensions for WP (DWP) andSP (DSP). The result indicated that DWP was largerthan DSP irrespective of the state of the filament(myosin-free or bound) and that both parameters formyosin-bound filaments were significantly largerthan those for myosin-free filaments. This work is thefirst quantitative insight into how conformational dis-order of actin monomers is correlated with themyosin-induced increase in flexibility of actin fila-ments along their length.this mode. They present examples of how aberrationschange the probe shape in three dimensions, and itwas found that off-axial aberrations may need to beconsidered for focal series of large areas. It was shownthat oversized or annular apertures theoreticallyimprove the vertical resolution for three-dimensionalimaging of nanoparticles. When imaging nanoparti-cles of several nanometers in size, regular scanningtransmission electron microscopy can thereby be opti-mized such that the vertical full-width at half-maxi-mum approaches that of the aberration-correctedSTEM with a standard aperture.26MICROSCOPY AND ANALYSIS NOVEMBER 2011CIRCLENO. 1 ORONLINEwww.microscopy-analysis.comThe cover shows a confocal image (top) of aDrosophilaembryo at stage 11, expressing the trachealmarker trh-LacZ (Cy3, red) and the cell membranemarker Dlg (Alexa 488, green).

Users can generate bright images athigher resolutions, since silicon oil significantly improvesoptical performance compared to water-based methodsand offers larger working distances than oil immersionobjectives. This maximises the effectiveness ofbrightfield, differential interference contrast,fluorescence, confocal laser scanning and multiphotonstudies. Silicon oil allows users to capture bright, highresolution images of living samples, even deep into cellsand tissues. This can be achieved because the refractiveindex of silicon oil (n = 1.40) is almost identical to thatof living biological samples (n =1.38 on average) sosilicon oil-immersion objectives minimise refractive indexmismatch and spherical aberration. This is a key factorfor improving the focal spot, which can be even furtheroptimised to correct for temperature changes byadjusting the available correction collar. The propertiesof silicon oil also make it ideal for long-term, time-lapsestudies since it is stable, viscous and of low volatility; itwill not dry out or absorb moisture over time. With its 30x magnification and high NA of 1.05, theUPLSAPO30xS delivers highly resolved images of anextensive sample area. The Olympus UPSLAPO60xSprovides increased magnification (60x) and NA (1.30),allowing researchers to produce highly detailed livesample images using fluorescence, confocal laserscanning and multiphoton excitation techniques. Thisobjective is also ideal for high resolution 3D imagingapplications by offering improved spherical aberrationcorrection and a shorter working distance of 0.3 mm.Please contact:OLYMPUS EUROPA HOLDING GMBHKatja AnsmannMarketing Communications ManagerTel: +49 40 2 37 73 - 5913Fax: +49 40 2 37 73 - 4784FEATURES9Bonding and TSV in 3D IC Integration: Physical Analysis witha Plasma FIB M M V Taklo, A Klumpp, P Ramm,L Kwakman and G Franz15Fracture Surface, Impact Energy and Hardness of Ni-FreeHigh-Mn Steels W Sha, H Haji Talib, E Wilson, R Rajendran,S Malinov, H Charlesworth, L Ibbitson21Variable Pressure Scanning Electron Microscopy of Viciafaba Stigmatic Papillae W Chen, F Stoddard and T BaldwinS5Atomic Resolution Secondary Electron Imaging in AberrationCorrected STEM H Inada, M Konno, K Tamura,Y Suzuki, K Nakamura, Y ZhuS11Development of a High Throughput Electron Microscope forNanoscale Analysis M Matsushita, S Kawai, T Iwama, K Tanaka,T Kuba, N Endo, T IsabellS19Low Beam-Energy Energy-Dispersive X-Ray Spectroscopy forNanotechnology P CamusS23Product Focus - Nanotechnology and Electron MicroscopyCOVER STORYMICROSCOPY & ANALYSISISSN 0958-1952 - UKISSN 2043-0655 - Europe© 2011 John Wiley & Sons, LtdIssued in: January, March, May, July, September, NovemberPublished by: John Wiley & Sons, Ltd, The Atrium, Southern Gate, Chichester, West Sussex PO19 8SQ, UK Tel: +44 (0)1243 770257 Fax: +44 (0)1243 770432Email: firstname.lastname@example.org Website: www.microscopy-analysis.comAssociate Editorial Director: Dr Ray J.
