Based on the integration and the convergence of MicroDysis' innovations in: (a) 3 dimensional microfabrication; (b) carbon nanotube functionalization and vertical assembly; and (c) fluidic array, MicroDysis has developed Fluidic nanoAssay with fluidic workstation for protein and molecular analysis. The prototype has been successfully demonstrated the feasibility for immobilization of antibody probes for analysis and detection of protein and other molecular biomarkers at fg/ml sensitivity.

Fluidic nanoAssay

The fluidic array consists of fluidic microchannels with SWNT detection spots on the top surface. The SWNT spots with COOH function groups on the nanotube surfaces can effectively immobilize oligo, antibody, and other biological probes by microfluidic liquid delivery, so that a fluidic array can be configured by the number of probes necessary to interrogate the desired number of targets, or the number of samples to be analyzed. For DNA analysis, a test can be based on a series of independent assays that indicate the presence or absence of each target gene sequence.  The fluidic array permits the use of multiple probes per gene imposing an unprecedented degree of stringency on the test, resulting in the practical elimination of false positive readings.
 
MicroDysis will soon demostrate the new development of Fluidic nanoAssay for early disease detection applications 

MicroDysis also develops and manufactures a wide variety of nanotube-based devices, fluidic devices and equipment for biomedical, pharmaceutical, and environmental applications, based on its patented micro- and nano-fabrication technology to enhance test sensitivity and reaction capability.

CONTROLLED FUNCTIONALIZED POROUS MEMBRANE
Controlled functionalized porous membrane (CFPM) is incompressible and very durable, does not shrink or swell in different solutions. It is able to be used as a solid support in filtration, purification, test kit, and solid phase reaction.
 
Its porous structure is distributed uniformly in XYZ directions with tortuous paths and controlled porosities from 1 to 50 microns.
 
The surface is functionalized with carboxyl (-COOH), hydroxyl (-OH) or amino (-NH2) groups.
   
Features:
  • Incompressible and durable
  • Highly Uniform Pore Structure
  • Porosities from 1 to 50 microns
  • Broad Chemical Resistance
  • Rich Functional Group, COOH, OH, or NH2
PERISTALTIC MICROPUMP
MicroDysis' micropump provides a unique miniature fluidic solution for lab and drug delivery applications, not only in its reliability, accuracy, small size, and low power consumption, but also in its unique design for consumable tube changes.
The pump uses an exchangeable and disposable tube cartridge where a flexible silicone tube is compressed by a series of shoes to induce liquid flow. The micropump is self-priming and requires little or no maintenance. The only material in contact with the liquid is the silicone tube, which makes wide fluid-compatible applications. 
   
Features:
  • Flow rate: 25 ul – 100 ul/min
  • Accuracy: +/- 2.5%
  • Pressure: 600 mmH2O
  • DC voltage: 2.25 – 3.6 V
  • Dimension: 15.5 x 21 x 29.5 mm
  • Weight: 7 g
