Featured Application

Non-invasive In-liquid Imaging by Ion Conductance Microscopy (ICM) 
With the existing research tools available in the market today, it has been virtually impossible to perform nanoscale imaging of single live cells. In particular, cellular membrane surfaces are transparent to optical microscopy methods, and too soft to produce any contrast or even endure probing by AFM method.  Ion Conductance Microscopy (ICM) is the only non-invasive in-liquid scanning probe technique that does not apply any force over its sample surface, making it ideal for nanoscale imaging of single live cells, in particular soft cellular membranes. It can be further adapted to enable a host of powerful applications in nano-manipulated electrophysiology and cell motility studies, whose examples include targeted localized stimulation, monitoring, and drug delivery at the cellular level. Click here for further information on the mechanism and applications of ICM.

Featured Product

XE-Bio: Cell Discovery Like Never Before
XE-Bioprovides the most detailed and integrated information on nanoscale biological surfaces available today, enabling breakthrough research on single live cells by connecting their detailed structural features to cellular functions. Distinguished researchers from Harvard Medical School, Johns Hopkins University, NIH and other major universities and research institutes expressed interest in the versatile use of ICM;ICM is the only non-invasive in-liquid scanning probe technique that does not apply any force over its sample surface, making it ideal for nanoscale imaging of soft cellular membranes. The ICM also enables localized functional studies on single live cells, including functional mapping on membrane features. Click here for the detailed product information.

News and Events

XE-Bio Brings Promise in the Fight against Hepatitis C.
Suwon, South Korea, Feb 12, 2010 - The fight against the liver disease hepatitis C has been something of an impasse for years, with more than 150 million people currently infected, and traditional antiviral treatments causing nasty side effects and often falling short ofa cure. Park Systems’ XE-Biohelped researchers at Stanford University discover a vulnerable step in the virus’ reproduction process that in lab testing could be effectively targeted with an obsolete antihistamine (Click here for the latest news of vaccine development for hepatitis C). XE-Bio successfully imaged and analyzed two of the compounds that most potently inhibit vesicle aggregation revealed their mechanism of action on 4BAH2 function. These results provide new insight into the molecular mechanism of HCV replication platform assembly, and demonstrate the utility of a novel small-molecule anti-HCV strategy.Click here for the rest of the news article. 

 Made the Cover of Microscopy and Analysis Magazine.
Suwon, South Korea, Feb 11, 2010 - Park Systems’ XE-3DM™ was featured on the front cover of Microscopy and Analysis (M&A) magazine. The 3D image of an overhang structure on the front cover was imaged with Park Systems’ new 3D atomic force microscope. The new XE-3DM™ is designed for overhang and trench profiles, sidewall roughness imaging, and critical angle measurements. Click here for the rest of the news article.

Images from Crosstalk Eliminated (XE) AFM

The image of a cancer cell of lung by XE-Bio
The surface of a live lung cancer cell that imaged in buffer solution using ion conductance microscope shows the rough surfacestructure typical of cancer cells.
  A traditional AFM is not capable of imaging such membrane structure (without fixation) due to the large interaction force between the tip and the sample.
