The conventional fabrication methods for microfluidic devices require cleanroom processes that are costly and time-consuming. We present a novel, facile, and low-cost method for rapid fabrication of polydimethylsiloxane (PDMS) molds and devices. The method consists of three main fabrication steps: female mold (FM), male mold (MM), and chip fabrication. We use a CO2 laser cutter to pattern a thi...

The silicon-based MEMS fabrication technology, including bulk micromachining and sacrificial layers technology have been developed and studied. The 3-D fabrication and integration of silicon-based MEMS and standard process fabrication have been studied in the present paper. 1 Introduction MEMS devices and systems offer advantages of small volume, light weight, low power, and the integration of ...

rapid prototyping (rp) is a technique of manufacturing parts by the additive layer manufacturing technology; where, a three-dimensional (3d) model created in a computer aided design (cad) system is sectioned into 2d profiles, which are further constructed by rp layer by layer. its use is not limited to industrial or engineering fields and has extended to the medical field for the manufacturing ...

most assay manufacturers take additional measures during the assay development. The most frequent procedure involves suppressing the non-specific binding with blocking reagents, which vary from normal mouse IgG to more refined formulations. Whilst in most cases these measures are adequate, they do result in additional costs in terms of both material and labor. The effect of HAMA can also be sup...

A decision maker faces a new theory of how certain events unfold over time. The theory matters for choices she needs to make, but possibly the theory is a fabrication. We show that there is a test which is guaranteed to pass a true theory, and which is also conservative: A false theory will only pass when adopting it over the decision maker’s initial theory would not cause substantial harm; if ...

We present ramped voltage data from a new nitride used in our fabrication process. Using the same fabrication flow, we measured increased lifetimes for capacitors using this new dielectric. Using the linear field model, this translates into capacitors that can sustain higher applied voltages before they fail.

Solid Freeform Fabrication (SFF), also referred to as Layered manufacturing (LM), is a new method of fabrication. Unlike conventional manufacturing (e.g., CNC machining), where a part is fabricated by selectively removing material from a workpiece, in SFF, a part is built by depositing material, layer-by-layer, under computer control. Solid Freeform Fabrication is in principle a 2.5D process st...

Objects and systems in nature are models for the practice of sustainable design and fabrication. From trees to bones, natural systems are characterized by the constant interplay of creation, environmental response, and analysis of current structural constituents, as part of a larger dynamic system. In contrast, traditional methods of digital design and fabrication are characterized by a linear ...
