Porous Membrane Chips

SiMPore’s suite of silicon nanomembranes and related Porous Membrane Chips enable novel applications in research and routine testing in the life, materials, and environmental sciences.

Membrane Configurations

Through a range of proprietary and industry-standard methods, we’re able to offer various membrane configurations to meet your unique needs. 

Nanoporous Silicon Nitride

Nanoporous Silicon Nitride (NPN)

Unmatched capabilities

SiMPore’s innovative nanoporous silicon nitride (NPN) provides unparalleled permeability, optical transparency, and precision pore sizes – all in the same membrane material.

Patented manufacturing

Through a patented manufacturing process, nanopores are randomly created within a Silicon Nitride (SiN) layer of nanometer thickness; this process produces a very high pore density and thus highly permeable membranes.

Reduces inefficiencies

These NPN membranes are atomically flat and chemically inert, enabling markedly reduced biofouling and nonspecific interactions across a wide array of sample types.

Microporous & Microslit Silicon Nitride

Microporous & Microslit Silicon Nitride (SiN)

Uniform design

SiMPore fabricates microporous and microslit membranes within low-stress silicon nitride layers deposited on prime-grade silicon wafers. These porous features are uniformly, photolithographically patterned and etched.

Resilient thickness

Current products offer 10-20% porosity in a robust 400 nm thick membrane for demanding flow-based applications.

Microporous G-FLAT® Silicon Dioxide

Microporous G-FLAT® Silicon Dioxide

Proprietary wrinkle-free substrate

Our microporous G-FLAT™ silicon oxide membranes are manufactured with a patented method, yielding a flat, porous, and glass-like layer. Current membranes are available with 5-20% porosity in a 300 nm thick membrane that is optically transparent.

Directly patterned

These membranes are directly patterned using photolithography, resulting in uniform pore sizes.

Custom Porous Membrane Chip Formats
