“…Colorimetry, including measurement of the wavelength and the intensity of electromagnetic radiation in the visible region of the spectrum, is extensively used for identification and determination of concentrations of substances that absorb light [ 61 ]. Colorimetric determination of lithium levels has been investigated by several studies [ 43 , 46 , 52 , 62 ].…”

Since the mid-20th century, lithium continues to be prescribed as a first-line mood stabilizer for the management of bipolar disorder (BD). However, lithium has a very narrow therapeutic index, and it is crucial to carefully monitor lithium plasma levels as concentrations greater than 1.2 mmol/L are potentially toxic and can be fatal. The quantification of lithium in clinical laboratories is performed by atomic absorption spectrometry, flame emission photometry, or conventional ion-selective electrodes. All these techniques are cumbersome and require frequent blood tests with consequent discomfort which results in patients evading treatment. Furthermore, the current techniques for lithium monitoring require highly qualified personnel and expensive equipment; hence, it is crucial to develop low-cost and easy-to-use devices for decentralized monitoring of lithium. The current paper seeks to review the pertinent literature rigorously and critically with a focus on different lithium-monitoring techniques which could lead towards the development of automatic and point-of-care analytical devices for lithium determination.

Biosensors are analytical devices combining a physical sensor with a part of biological origin providing sensitivity and selectivity toward analyte. Biological warfare agents are infectious microorganisms or toxins with the capability to harm or kill humans. They can be produced and spread by a military or misused by a terrorist group. For example, Bacillus anthracis, Francisella tularensis, Brucella sp., Yersinia pestis, staphylococcal enterotoxin B, botulinum toxin and orthopoxviruses are typical biological warfare agents. Biosensors for biological warfare agents serve as simple but reliable analytical tools for the both field and laboratory assay. There are examples of commercially available biosensors, but research and development of new types continue and their application in praxis can be expected in the future. This review summarizes the facts and role of biosensors in the biological warfare agents’ assay, and shows current commercially available devices and trends in research of the news. Survey of actual literature is provided.

“…One of the main advantages of a flatbed scanner is the high stability of the analytical signal measurement conditions. , On the other hand, a smartphone combines the functions of a rudimentary monochromator, detector, recording device, and means for processing measurement results in one compact stand-alone module. Although some publications describe the construction of homemade optical measuring devices from separate electronic componentslight-emitting diodes, photodiodes, and multimeters, etc. − the development of optical analyzers based on smartphones and scanners , seems to be a more universal solution for various educational institutions, since they are widespread and affordable.…”

Technically simple and extremely cheap setups for colorimetric and fluorimetric analyses using a smartphone camera are presented. Laboratory activities on digital colorimetric and fluorimetric analyses for students of secondary and higher educational institutions are proposed, namely, photocolorimetric determination of acetylsalicylic acid in Cardiomagnyl and copper and nickel in nickel−silver alloy, and fluorimetric determination of riboflavin mononucleotide in its injection solution. Nickel and copper in nickel−silver are determined simultaneously; i.e., two-component colorimetric analysis is performed, which allows the introduction of linear regression analysis to students. The use of the developed setups and activities can help to form the students' skills of a meaningful choice of the conditions for measuring the analytical signal to achieve the required metrological characteristics of the determination results.
