“…In contrast to specific targeting, multi-analyte sensing aims to perform discrimination among multiple structure-or propertysimilar analytes, with detectable and differential signal outputs. 95 A key point to the research of sensor arrays is to reduce the sensing molecules and minimize the arrays. 93 The chemical nose consists of sensor arrays, in which a series of responsive and non-specific sensing molecules are invested.…”

Photochromic sensors are widely used in detecting and monitoring analytes. Due to the photoswitchable properties, photochromic sensors show advantages in providing more recognition states and sensing information, and thus better sensitivity to external stimulations. Via reasonable design of photochromic sensors with various ionophores, dyes, platforms and metallic complexations, it is promising to achieve visual, sensitive and high-throughput detection. In this review, we summarized the applications of photochromic sensors in the areas of specific recognition and multi-analyte discrimination, based on their isomerization to light, as well as pH, temperature, solvent, etc. Specially, the multi-analyte determination was introduced, which has aroused extensive interest in recent years.

Chemical sensors have been essential components in recent years due to the gathering attention in environmental monitoring and healthcare. In this review, the authors comprehensively highlight recent progresses on the 1D chemiresistive-type sensors based on semiconductor metal oxides (SMOs) and optical-type sensors, which are prepared by electrospinning technique. In the part of chemiresistive-type sensors, diverse synthesis techniques for 1D SMO nanofibrous structure are presented with controlled microstructure and surface morphology. In addition, unique functionalization routes of emerging nanocatalysts encapsulated by bio-inspired templates are described for the next generation catalyst on the 1D SMO nanofibers (NFs). For the optical-type sensors, new classes of 1D NFs employing specific absorption and emission properties are introduced. In particular, diverse 1D NF-based colorimetric and fluorescence sensors as well as Raman and surface-enhanced Raman scattering sensors are covered in the view point of material preparation and optical sensing properties. Finally, the authors prospect future research directions to overcome current limitations and challenges to achieve high performance chemical sensors.

“…Various sensor arrays for heavy-metal-ion detection using commercial or custom fluorescent indicators have been reported that manifest remarkable selectivity at mM concentrations of the ions. However, extending this performance to the environmentally relevant M concentrations remains a challenge because of the lack of suitable fluorescent indicators [3,[20][21][22][23][24].…”
