“…[81] The second property of interest to us is that optical forces provide a fundamental property of light to develop a practical platform to study processes within the cell, overcoming the need for fluorescent staining. [82][83][84] This property allows natural label-free characterization of biological processes. Recent studies illustrate the feasibility of utilizing optical forces for instance: in vesicles (size from tens to thousands of nanometers), [85,86] in manipulating and dragging a selection of liquid domains in lipid bilayers, [87] in trapping viruses (thousands of nanometers), [88] and in trapping, [21,22,89] sorting, [90] and isolation [91] of bacteria and living cells.…”

Advanced photonic tools may enable researchers and clinicians to visualize, track, control, and manipulate biological processes at the single‐cell level in space and time. Biological systems are complex and highly organized on both spatial and temporal levels. If biological entities are to be studied, perturbed, engineered, or healed, key‐players in such systems must be visualized and it is required to track, control, and manipulate them precisely and selectively. To achieve this goal, the engineering of nondestructive tools allows to interrogate and manipulate the function of proteins, pathways, and cells for physicians, enabling the design of “smart materials” that can direct and respond to biological processes. Among the potentially exploitable nondestructive tools, light‐based actuation is particularly desirable. It enables high spatial and temporal resolution, dosage control, minimal disturbance to biological systems, and deep tissue penetration. Herein, existing approaches toward the engineering of light‐activated tools for the interrogation and manipulation of single‐cell processes are overviewed, and the types of studies and types of functions that can be controlled by light are listed. Timely applications, such as studies of inflammation and crossing brain barrier systems—via super‐resolution imaging and optomechanical manipulation—are two representative examples of emerging applications so far never addressed.

“…The Purcell effect involves the enhancement of the radiative decay rate, which in return, can lead to a quantum yield enhancement by the plasmon resonance at the emission wavelength. 20 The spontaneous radiative decay rate enhancement arises from the large radiative local density of optical states, due to the confinement of the emission field in the vicinity of the plasmonic nanostuctures. 21 Notably, the radiative decay rate enhancement (Purcell effect) occurs when plasmon resonance frequency overlaps with the PL spectrum of the fluorophore.…”

“…These systems involve the emission of light resulting from a chemical reaction thus offering the advantages of high sensitivity, low background noise, and compatibility with imaging techniques. One promising approach to enhance CL involves the utilization of silver nanoparticles (Ag NPs), which can improve the light emission and provide unique properties for a range of applications, including nucleic acid (NA) detection [4,5]. CL is typically achieved through the oxidation of a CL substrate triggered by an enzyme or a catalyst.…”

One of the most critical issues in the field of molecular diagnostics and medicine is the development of compact and sensitive assay devices for the precise detection of nucleic acids. Although there are several effective methods for detecting unique nucleic acid sequences, the high cost of equipment and reagents, as well as the need for highly trained personnel, necessitate the design of new and more affordable diagnostic assays that are comparable in selectivity and sensitivity to existing methods that can be used in developing countries and/or outside of specialized diagnostic laboratories. Sensing methods based on guanine quadruplexes (G-4)/hemin complexes, that have peroxidase activity are one of the promising directions for the detection of target nucleic acids. Target nucleic acid was analyzed by peroxidase-like DNA-nanomachine (PxDm) equipped with 1-3 long analyte binding arms to tightly bind and unwind single-stranded analytes. In this study, we present a technique for sequence-specific detection of nucleic acid. The technique is based on the measuring of a chemiluminescent (CL) emission induced by luminol oxidation utilizing a closed-type detection device. Moreover, the optical properties and potential use of plasmonic silver nanoparticles (Ag NPs) to enhance the CL intensity of chemiluminophore were investigated. Particular attention was paid to the possibility of synthesizing the silver nanoparticles with different spectral positions of plasmon resonance band, depending on the method and duration of synthesis. The CL intensity of luminol in the presence of the post-centrifuged colloidal Ag NPs obtained by laser ablation has been increased 3 times. The combination of AgNPs-luminol-DNA-nanomachine systems in the presence of a target analyte led to the significant increase of limit of detection and reached clinically relevant quantitative indications.
