“…Using a TLM and a fluid micro-chip sample holder, they were able to detect DNA at the lowest concentration of 27 nM. Gold nano-particles detection limits have been also studied in water by Lima et al [78], who found possible to detect the presence of a single particle of 50 nm diameter. Another micro-fluidic TLM detection of traces of 2,4,6-trinitrotoluene (TNT) was presented by Yoosefian and Alizadeh [79].…”

The thermal lens formed in a thermo-optical material as a result of its inhomogeneous heating, is a well-known phenomenon that has found widespread interest in the last decades, especially in the field of laser engineering and photo-thermal spectroscopy. In recent years, growing interest in the application of thermal lensing in different fields of optics and material studies has been observed. This review summarizes the latest efforts made by the scientific community to develop ways of using the phenomenon of thermal lensing. Its applications in spectroscopy, in laser beam formation and in imaging are described. The advantages and disadvantages of the thermal lensing in regard to these areas along with the potential future applications of the phenomenon are discussed.

Microfluidic approaches to nanomaterial synthesis provide an effective means of making high quality products, with exquisite control over electronic, optical, and structural properties. Furthermore, microfluidic reactors integrating analytics and real‐time reaction control have recently emerged as powerful tools in automating materials exploration and reaction parameter mapping, with a rapidity and efficiency that is inaccessible to traditional flask‐based methods. Herein, the recent innovations in the microfluidic synthesis of photonic nanoparticles, whose varied luminescent and plasmonic properties have found great application in the biomedical and optoelectronic sciences, are presented. Special attention is placed on the achievements and promise of microfluidic approaches in automated multidimensional reaction parameter screening employing in situ optical characterization. In an extended outlook, the future of the field is explored, looking toward the integration of smart control systems and machine learning algorithms, and demonstrating how maximal positive impact can be achieved. Far from degrading or replacing the ingenuity of the experimentalist, these tools will provide new powers of exploration, augmenting the discovery process. Further, through automation and miniaturization, it is expected that such approaches will fulfill the moral imperative of maximizing the benefit derived from the natural resources consumed in conducting research.
