“…In particular, geometrically chiral plasmonic structures have been used to tailor and tune the far-and near-field chiroptical responses [25][26][27][28][29][30][31][32][33][34][35][36][37]. The interaction of plasmonic enhanced chiral near-field with a chiral molecule is favorable to optimize the selective light absorption by the molecule, which in turn optimizes the corresponding CD signal [38][39][40][41][42]. We review here the recent trends in chiral plasmonic systems for enantioselective probing of biomolecules, with emphasis on the limitations of the systems reported so far.…”

There has been growing interest in using strong field enhancement and light localization in plasmonic nanostructures to control the polarization properties of light. Various experimental techniques are now used to fabricate twisted metallic nanoparticles and metasurfaces, where strongly enhanced chiral near-fields are used to intensify circular dichroism (CD) signals. In this review, state-of-the-art strategies to develop such chiral plasmonic nanoparticles and metasurfaces are summarized, with emphasis on the most recent trends for the design and development of functionalizable surfaces. The major objective is to perform enantiomer selection which is relevant in pharmaceutical applications and for biosensing. Enhanced sensing capabilities are key for the design and manufacture of lab-on-a-chip devices, commonly named point-of-care biosensing devices, which are promising for next-generation healthcare systems.

“…These characterization can be achieved by various instrumental techniques. In this context, ultraviolet-visible spectroscopy (UV-visible spectroscopy) has been very useful to rapidly detect the formation of different metal nanoparticles (silver, copper, gold, and platinum nanoparticles) since the surface plasmon resonance (SPR) phenomenon can be measured [118]. For the case of shape, size, morphology, and particle size distribution of metal nanoparticles, transmission electron microscopy (TEM), high-resolution electron microscopy (HRTEM), scanning electron microscopy, atomic force microscopy (AFM), and dynamic light scattering are suitable techniques that have been used to measure these physical properties of metal nanoparticles [117,[119][120][121][122][123][124].…”

Bacterial exopolysaccharides (EPSs) are biomolecules secreted in the extracellular space and have diverse biological functionalities, such as environmental protection, surface adherence, and cellular interactions. EPSs have been found to be biocompatible and eco-friendly, therefore making them suitable for applications in many areas of study and various industrial products. Recently, synthesis and stabilization of metal nanoparticles have been of interest because their usefulness for many biomedical applications, such as antimicrobials, anticancer drugs, antioxidants, drug delivery systems, chemical sensors, contrast agents, and as catalysts. In this context, bacterial EPSs have been explored as agents to aid in a greener production of a myriad of metal nanoparticles, since they have the ability to reduce metal ions to form nanoparticles and stabilize them acting as capping agents. In addition, by incorporating EPS to the metal nanoparticles, the EPS confers them biocompatibility. Thus, the present review describes the main bacterial EPS utilized in the synthesis and stabilization of metal nanoparticles, the mechanisms involved in this process, and the different applications of these nanoparticles, emphasizing in their biomedical applications.

“…One of the most significant properties of the MNPs for biosensor applications is their electromagnetic (EM) fields generated by free electrons around nanoparticles. This property can induce localized surface plasmon resonance (LSPR), which is induced by the irradiation of light and the excited free electrons simultaneously producing collective consistent oscillations [27][28][29][30][31]. LSPR on MNPs such as Au and Ag exhibited unique features underlying their strong absorption and scattering of light, making MNPs attractive candidates for the nanoprobes of the several biomolecules.…”

The biosensing platform is noteworthy for high sensitivity and precise detection of target analytes, which are related to the status of cells or specific diseases. The modification of the transducers with metallic nanoparticles (MNPs) has attracted attention owing to excellent features such as improved sensitivity and selectivity. Moreover, the incorporation of MNPs into biosensing systems may increase the speed and the capability of the biosensors. In this review, we introduce the current progress of the developed cell-based biosensors, cell chip, based on the unique physiochemical features of MNPs. Mainly, we focus on optical intra/extracellular biosensing methods, including fluorescence, localized surface plasmon resonance (LSPR), and surface-enhanced Raman spectroscopy (SERS) based on the coupling of MNPs. We believe that the topics discussed here are useful and able to provide a guideline in the development of new MNP-based cell chip platforms for pharmaceutical applications such as drug screening and toxicological tests in the near future.
