With the increasing public awareness of the impact of particulate matter (PM) on human
health, real-time monitoring of PM exposure level has attracted more interest than ever …

In the development of chemical analysis systems a clear trend exists towards miniaturization
using silicon micromachining. This paper reports on microflow devices such as microvalves …

This paper reports a micro gas chromatography (μGC) system that includes a
microfabricated Knudsen pump, preconcentrator, separation column, and discharge-based …

We report on a small (20× 10 mm) micromachined device for the detection of gases in micro-
gas chromatography (GC). It incorporates a micro-discharge across a 20-μm gap, and a …

Microfabricated semiconductor devices are becoming increasingly relevant also for (bio‐)
chemical sensors. The techniques will have a crucial impact in application fields such as …

The efficient and selective detection of volatile organic compounds (VOCs) provides key
information for various purposes ranging from the toxicological analysis of indoor/outdoor …

On-chip polymerase chain reaction (PCR) is beginning to provide a viable alternative to
conventional genetic profiling and amplification devices through minimal reagent use, short …

We report a smartphone compatible, low-cost porous silicon biosensor, which correlates the
structural colour of a porous silicon microcavity (PSiM) to spectral peak position. Molecules …

In order to fabricate microsensors, a micromachining, microfabrication technique based on
LSI technologies has been used. In this paper, useful micromachining techniques are …

A novel approach to analysis of complex gaseous mixtures is presented. The approach is
based on the utilization of a compact gas chromatograph in combination with an array of …
