“…However, the use of high-generation dendrimers for AgNP stabilization is often economically unviable for commercial purposes. To address this challenge, Lataifeh et al proposed a cost-effective method [ 121 ]. They introduced low-generation l -glutamic acid peptide dendrimers, which self-assemble on the surface of AgNPs, providing both stabilization and a consistent spherical shape to the NPs [ 121 ].…”

“…Thus, doing some exterior modifications, like PEG coating (Haque et al, 2017 ), is normal to reduce the surface charges; or changing the composition in the middle, namely incorporation modification, thus making a loosened distribution of

and forming a new structure, such as G3KL ( Figure 4A ), which is a third-generation dendrimer consisting of lysine as branch monomer and two leucine monomers incorporating inside (Gan et al, 2019 ). Moreover, PLLDs could be used as a modifier coating on some magnetic particles (Shen et al, 2017 ; Lataifeh and Kraatz, 2019 ) or linking with some block polymers enlarging LBD's zone area (Zhou et al, 2016 ). Considering these different types of modification, the structure of LBD is complicated and suitable for using in different applications.…”

With the advantages in biocompatibility, antimicrobial ability, and comparative facile synthesis technology, poly-L-lysine (PLL) has received considerable attention in recent years. Different arrangement forms and structures of the backbone endow lysine-based polymers with versatile applications, especially for ε-poly-L-lysine (EPL) and lysine-based dendrimer (LBD) compounds. This review summarized the advanced development of the synthesis and modification strategies of EPL and LBD, focus on the modification of bio-synthesis and artificial synthesis, respectively. Meanwhile, biomedical fields, where EPL and LBD are mainly utilized, such as agents, adjuvants, or carriers to anti-pathogen or used in tumor or gene therapies, are also introduced. With the deeper of knowledge of pharmacodynamics and pharmacokinetics of the drug system, the design and synthesis of these drugs can be further optimized. Furthermore, the performances of combination with other advanced methodologies and technologies demonstrated that challenges, such as scale production and high expenses, will not hinder the prospective future of lysine-based polymers.

“…Recently, a growing body of literature has extensively studied and evaluated several self-assembly approaches in SERS studies [ 8 , 9 , 10 ]. Currently, different techniques are being used to arrange self-assembled AgNPs over a large area, thanks to polymers [ 11 , 12 , 13 , 14 , 15 ], block copolymers [ 16 , 17 , 18 ], dendrimers [ 19 ], proteins [ 20 ], and deoxyribonucleic acid (DNA) molecules [ 21 , 22 ] acting as matrices for inducing ordering and anisotropic orientation on surfaces, and for controlling the number of constituent particles and their separation.

This work describes a novel, one-shot strategy to fabricate ultrasensitive SERS sensors based on silver/poly(methyl methacrylate) (PMMA) nanocomposites. Upon spin coating of a dispersion of PMMA and silver precursor on N-doped silicon substrate, closely separated silver nanoparticles were self-assembled into uniform nanospheres. As a result, a thin hydrophobic PMMA layer embedded with Ag nanoparticles (AgNPs) was obtained on the whole silicon substrate. Consequently, a large-scale, reproducible SERS platform was produced through a rapid, simple, low-cost, and high-throughput technology. In addition, reproducible SERS features and high SERS enhancement factors were determined (SEF ~1015). This finding matches the highest SEF reported in literature to date (1014) for silver aggregates. The potential and novelty of this synthesis is that no reducing agent or copolymer was used, nor was any preliminary functionalization of the surface carried out. In addition, the AgNPs were fabricated directly on the substrate’s surface; consequently, there was no need for polymer etching. Then, the synthetic method was successfully applied to prepare opaque SERS platforms. Opaque surfaces are needed in photonic devices because of the absence of secondary back reflection, which makes optical analysis and applications easier.
