CCD-camera based capillary chemiluminescent detection of retinol binding protein

Proposition of a simple method for chromium (VI) determination in soils from remote places applying digital images: A case study from Brazilian Antarctic Station

“…Digital image analyses are found for analytical methods in different matrices [17][18][19][20][21][22][23][24][25][26][27][28][29][30] and also for environmental monitoring and remote sensing [31,32]. For instance, Paciornik et al [31] quantified Hg in fish samples using analysis of color descriptors (Hue-Lightness-Saturation, HLS and Cyan-MagentaYellow, CMY) from digital images of a spot test system.…”

Extremely integrated device for high sensitive quantitative biosensing

“…Others solid state detectors could also be considered, like CMOS photodiodes, Avalanche photodiodes, etc [21][22][23][24][25]. A straightforward comparison of the efficiency of different systems is not always possible because of the varying targeted reactions and biomarkers (glucose, lactate, cells, etc) and their typical concentrations in the analytical sample, as well as the different methods (chemiluminescence, fluorescence, electroluminescence, etc) and purposes (e.g.…”

“…wearable or disposable device or laboratory instruments) involved. In [24], for example, which discusses an ELISA test with very good sensitivity, a CCD camera cooled at −45 • C is used in combination with chemiluminescence and immobilization of antibodies in capillary tubes.…”

Portable system for photodiode-based electrochemiluminescence measurement with improved limit of detection

“…However, their size, supply voltage and power consumption are too high to be used in portable instruments. Another alternative are CCD cameras, as reported Momeni et al [14]. The main disadvantage of CCD cameras is that they need to work at temperatures of tens of Celsius degrees below 0º to achieve a good resolution; they are also complex to use and process, making them of limited interest for portable instruments.…”
