“…Since late log phase and stationary phase bacteria were physiologically mature to some extent and might have better metal resistance and biological activities, they were chosen as the candidate matrices to study CdSe nanoparticle biosynthesis. 32 As shown in Fig. 6A , fluorescence intensity of the S. aureus increased with the relevant growth stage of the biological matrices from lag to stationary ones and reached maximum fluorescence emission when 12 h grown bacteria were used.…”

“…The ‘space–time coupling ARLCS strategy’ was first proposed to account for the synthesis of CdSe QDs in S. cerevisiae in 2009 [ 5 , 8 , 26 , 28 , 39 , 40 ], and it has been expanded to the synthesis of various nanocrystals, such as CdTe, ZnSe, CuSe and Te nanorods, in other cell types including Staphylococcus aureus [ 41 – 43 ], Fusarium oxysporum [ 44 ], E. coli [ 45 ], S. oneidensis [ 11 , 15 , 46 ], Bacillus licheniformis [ 47 ], B acillus amyloliquefaciens [ 48 ], Rhodotorula mucilaginosa [ 49 ], Candida utilis [ 50 ], mammalian cells [ 51 ], Tetrahymena pyriformis [ 52 , 53 ], Caenorhabditis elegans [ 54 ] and earthworms [ 38 , 55 ], by easily altering the raw chemicals fed to the cells (Fig. 1 ).…”

Live cells, as reservoirs of biochemical reactions, can serve as amazing integrated chemical plants where precursor formation, nucleation and growth of nanocrystals, and functional assembly can be carried out accurately following an artificial program. It is crucial but challenging to deliberately direct intracellular pathways to synthesize desired nanocrystals that cannot be produced naturally in cells, because the relevant reactions exist in different spatiotemporal dimensions and will never encounter spontaneously. This article summarizes progress in the introduction of inorganic functional nanocrystals into live cells via the ‘artificial-regulated space–time-coupled live-cell synthesis’ strategy. We also describe ingenious bio-applications of the nanocrystal–cell systems, and quasi-biosynthesis strategies expanded from live-cell synthesis. Artificial-regulated live-cell synthesis—which involves the interdisciplinary application of biology, chemistry, nanoscience and medicine—will enable researchers to better exploit the unanticipated potentialities of live cells and open up new directions in synthetic biology.

“…Hence, the focus of researchers shifted toward the fluorescence-based probes are sensitive, reliable and quick and Figure 4 Sensors and various tribological domains can be used for online metallic ion probe (Aydin, 2020;Kong et al, 2020). Until this date, the fluorescent probes coupled with carbonbased quantum dots and semiconductor quantum dots have been widely used to detect the metallic ions or specifically Cu 21 in the lubricating oil (Milindanuth and Pisitsak, 2018;Yu et al, 2018;Yan et al, 2018). Recently, researchers have used the CsPbBr 3 perovskite quantum dots in the fluorescence probe to detect the presence of Cu 21 (Gao et al, 2020).…”

Purpose The involvement of wear, friction and lubrication in engineering systems and industrial applications makes it imperative to study the various aspects of tribology in relation with advanced technologies and concepts. The concept of Industry 4.0 and its implementation further faces a lot of barriers, particularly in developing economies. Real-time and reliable data is an important enabler for the implementation of the concept of Industry 4.0. For availability of reliable and real-time data about various tribological systems is crucial in applying the various concepts of Industry 4.0. This paper aims to attempt to highlight the role of sensors related to friction, wear and lubrication in implementing Industry 4.0 in various tribology-related industries and equipment. Design/methodology/approach A through literature review has been done to study the interrelationships between the availability of tribology-related data and implementation of Industry 4.0 are also discussed. Relevant and recent research papers from prominent databases have been included. A detailed overview about the various types of sensors used in generating tribological data is also presented. Some studies related to the application of machine learning and artificial intelligence (AI) are also included in the paper. A discussion on fault diagnosis and cyber physical systems in connection with tribology has also been included. Findings Industry 4.0 and tribology are interconnected through various means and the various pillars of Industry 4.0 such as big data, AI can effectively be implemented in various tribological systems. Data is an important parameter in the effective application of concepts of Industry 4.0 in the tribological environment. Sensors have a vital role to play in the implementation of Industry 4.0 in tribological systems. Determining the machine health, carrying out maintenance in off-shore and remote mechanical systems is possible by applying online-real-time data acquisition. Originality/value The paper tries to relate the pillars of Industry 4.0 with various aspects of tribology. The paper is a first of its kind wherein the interdisciplinary field of tribology has been linked with Industry 4.0. The paper also highlights the role of sensors in generating tribological data related to the critical parameters, such as wear rate, coefficient of friction, surface roughness which is critical in implementing the various pillars of Industry 4.0.
