Applications

Mad City Labs, Inc nanopositioning systems, micropositioning systems, instrument solutions, and piezoactuators are used for a variety of applications. The following categories represent a few of the most popular applications for nanopositioners and nanopositioning systems.

Super-resolution microscopy is a blanket term used to describe several newly emerging forms of light microscopy, each of which surpasses the classical diffraction limit as described by Ernst Abbe.  While conventional light microscopy attains resolving power of about 250nm, these SR techniques enable resolutions of tens of nanometers.

The SR methods depend on photo-physical properties displayed by particular fluorescent probes used to mark the particular process of interest.  The fluorescent state of these probes can be proactively manipulated by exposure to specific wavelengths of light.  SR microscopy exploits these probe properties to either spatially restrict (STED, SSIM), or temporally separate (STORM, PALM) the photons emitted by two closely spaced fluorescent sources so that they can be imaged separately, and in doing so circumvents the diffraction limit.

The SR methods show great promise to enable unprecedented views into the dynamic world of the cell at the nanometer scale.  However, these SR imaging techniques place a great premium on the stability of the imaging system, and as the SR methods make their way into common use, a “stability limit” may replace the diffraction limit on resolving power.

Mad City Labs offers several products designed to achieve ultra-high stability in an imaging system through active feedback compensation of measured system drift.

Scanning Probe Microscopy (SPM) refers to a category of microscopy techniques that form images of surfaces using a physical probe that scans a sample.  Examples of commonly used probes are tungsten tips and the Akiyama probe.  An image of the surface is obtained by mechanically moving the probe in a raster scan of the sample and recording the probe-surface interaction as a function of position.   Atomic, and even sub-atomic, resolution can be achieved by many SPM techniques largely due to the characteristics of the piezo-actuated motion control used in SPM instruments.

Mad City Labs offers a high-resolution, closed loop nanopositioning systems well suited to atomic force microscopy (AFM), near field scanning optical microscopy (NSOM), and other SPM applications.  Our recently developed product, MadPLL®, offers users the ability to assemble a robust, inexpensive SPM system for use in a variety of environments.

Optical Tweezers & Optical Traps

Optical tweezers are capable of manipulating nanometer and micrometer-sized dielectric particles by exerting extremely small (piconewton) forces via a highly focused laser beam. Optical traps are very sensitive instruments and are capable of the manipulation and detection of sub-nanometer displacements for sub-micron dielectric particles. (Ref. Moffitt JR, Chemla YR, Izhaky D, Bustamante C [2006]. Differential detection of dual traps improves the spatial resolution of optical tweezers. Proc. Natl. Acad. Sci. U.S.A. 103 (24): 9006–9011.)  They have been used to manipulate and study single molecules by interacting with a bead that has been attached to that molecule. DNA and the proteins and enzymes that interact with it have been studied in this way.

Most optical traps are operated such that the dielectric particle rarely moves far from the trap center. The reason for this is that the force applied to the particle is linear with respect to its displacement from the center of the trap provided the displacement is small. In this way, an optical trap can be compared to a simple spring, which follows Hooke's law.  The particle position can be maintained by either precisely moving the sample or moving the trap itself. 

Mad City Labs produces nanopositioning systems with sub-nanometer precision that enable the particle to remain centered and beam steering nanopositioning systems which can control the laser beam path and hence the location of the optical trap.
