“…In particular, there are related optoelectronic techniques and nonoptical electric deposition techniques on ferroelectric substrates that take advantage of charge distributions similar to the PVT ones for particle arranging. One may point out pyroelectric and ferroelectric domain-based trapping of biological [36,37] and inorganic [6,38] matter and photoinduced Ag-NP deposition from Ag þ on Fe∶LiNbO 3 [39].…”

Currently, there is increasing interest from many scientific disciplines in the development of systems that are able to sort and arrange many objects in parallel at the nano-and micrometric scale. Among others, photovoltaic tweezers (PVT) are an optoelectronic technique for trapping and patterning nano-and microobjects in accordance with an arbitrary light profile. In this work, the differential features of electro-and dielectrophoretic (EP and DEP) nanoparticle (NP) patterning using PVT are deeply investigated. The study is carried out through theory and experiments. The developed theory extends the applicability of a previously reported model to be able to compute EP potentials and to obtain numerical values for the EP and DEP potential energies. Two-dimensional patterns of charged and neutral aluminum NPs are fabricated on top of Fe∶LiNbO 3 crystals, and different light distributions and other experimental parameters (crystal thickness and NP concentration) are compared. Patterns of charged and neutral NPs show remarkable differences in both particle density distribution and fidelity to the original light profile. The observed different features between EP and DEP trapping are satisfactorily explained by the theoretical analysis. The results provide routes for the optimization of the NP arrangements for both regimes.

Nanomaterials manipulation using dielectrophoresis (DEP) is one of the major research areas that could potentially benefit the micro/nano science for diverse applications, such as microfluidics, nanomachine, and biosensor. The innovation and development of basic theories, methods or applications will have a huge impact on the entire related field. Specifically, for DEP manipulation of nanomaterials, improvements in comprehensive performance of accuracy, flexibility and scale could promote broader applications in micro/nano science. Therefore, to explore the directions for future research, this paper critically provides an overview on the fundamentals, recent progress, current challenges, and potential applications of DEP manipulation of nanomaterials. This review will also act as a guide and reference for researchers to explore promising applications in relevant research.

“…Among others, excimer laser irradiation of metal films has been reported to produce Ag‐nanoislands arranged in self‐organized patterns, which presents LSPR. Other relatively simple methods consist on precipitating Ag‐nanoparticles in the frontiers of a periodically poled ferroelectric pattern under uniform UV light illumination or taking advantage of the pyroelectric effect . In this way, relevant enhancements in the SHG response have been obtained which are associated to the LSPR of the structures …”
