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

Metal-organic framework (MOF) based composites are advantageous for the development of
chemoresistive sensors for gases owing to their high selectivity, sensitivity, and low …

Ozone is currently the main atmospheric pollutant in the Pearl River Delta region, China.
The atmospheric volatile organic compounds (VOCs) are key participators in the formation of …

Ag nanorods coated with an ultrathin HfO2 shell (Ag NRs@ HfO2) were prepared for the
synthesis of a versatile, robust, and easily recyclable surface-enhanced Raman scattering …

A photonic crystal (PC) sensor that can selectively detect organic vapors through visual color
changes has been proposed. The sensor was fabricated by infiltrating a tetraphenylethene …

In this paper, we report multiplex SERS based VOCs detection with a leaning nano-pillar
substrate. The VOCs analyte molecules adsorbed at the tips of the nano-pillars produced …

Urinary benzene, toluene, ethylbenzene, and xylenes (BTEX) can be used as a reliable
biomarker of exposure to these pollutants. This cross-sectional study aimed to employ …

In this paper, we present surface-enhanced Raman scattering (SERS)-based volatile
organic compounds (VOCs) detection with bimetallic nanogap structure substrate. Deep UV …

To mimic the human olfactory system, an electronic nose (E-nose, also known as artificial
olfactory) has been proposed based on a multiple gas sensor array and a pattern …

This paper reports an optical fiber toluene sensor based on whispering gallery mode (WGM)
microbottle resonator. The sensor includes a single-mode fiber (SMF)-no-core fiber (NCF) …
