New Manuscript Accepted: Nat. Commun. 14, 6996 (2023).

Manuscript titled “Efficient optical plasmonic tweezer-controlled single-molecule SERS characterization of pH-dependent amylin species in aqueous milieus” by Fu and Chi et al was accepted for publication as full paper in Nature Communications

https://doi.org/10.1038/s41467-023-42812-3

Oct 21, 2023

In this work, we construct a simple plasmonic junction between two silver nanoparticle-coated silica microbeads to exert optical plasmonic trapping upon on/off laser excitation to control the formation of dynamic nanocavity with high turnover efficiency. Since both optical plasmonic trapping and SERS techniques are surface-sensitive relying on nanostructured substrates, it overcomes the optical diffraction limit to confine the position of the plasmonic nanocavity and reduce the SERS active-detection volume for huge SERS enhancements at the single-molecule sensitivity. More importantly, it is the first time to use on-and-off trapping control of a dynamic nanocavity to enlarge high-throughput sampling capacity for efficient single-molecule SERS detections and characterize pH-dependent amylin (hIAPP) species with statistically significant sampling sizes. Statistics of its structural features at the single-molecule level reconstructs its ensemble structures and brings unique information on population and probability of different conformations, which could directly establish the linkage between SERS characterizations and MD simulations to reveal the structural heterogeneity of amylin.

May 9, 2023

Supramolecular Materials is a publication of peer-reviewed research. It covers all aspects of these materials, which are based on supramolecular interactions or self-assembly. The journal welcomes submissions of research articles/communications, perspectives/concepts, and reviews on both fundamental insight into supramolecular interactions, and demonstrations of functional supramolecular systems. The journal publishes research on design/fabrication/characterization of non-covalently interactive supramolecular systems, with diverse features such as being dynamic, reversible, self-adaptive, stimulus-responsive etc.

Manuscript titled “Tunable lipid-coated nanoporous silver sheet for characterization of protein-membrane interactions by surface-enhanced Raman scattering (SERS)” was accepted for publication in Analytical and Bioanalytical Chemistry.

https://doi.org/10.1007/s00216-023-04701-y

Apr 12, 2023

In this work, we develop an analytical platform that provides consistent SERS enhancements and enables independent control of specific membrane properties, in particular, lipid packing defects, to directly characterize protein structures, leveraging the precise controllability of lipid lateral pressure by a Langmuir–Blodgett (LB) technique and the sensitive detection capability of nanoporous-based SERS substrate. Interestingly, alpha-synuclein folded into the alpha-helical structure on negatively charged lipid heads, while the exposure of hydrophobic lipid tails induced its beta-sheet formation in both monolayer lipid tails and low-pressure liquid phase lipid bilayer, which might be linked to its misfolded states for membrane disruptions associated with Parkinson’s disease.

Alzforum, etc.).

https://doi.org/10.1038/s41467-021-21543-3

Jan 28, 2021

In this work, we integrate optical tweezers manipulation and Raman spectroscopic detection into a novel platform to create, visualize, and manipulate hotspot between two Ag nanoparticle-coated silica beads, making it convenient to precisely control and adjust SERS enhancement in the real time to achieve tunable and reproducible SERS enhancements. With the single-molecule sensitivity, this new approach addresses the challenges in identifying protein structures at low concentrations. For example, alpha-synuclein is a typical intrinsically disordered protein that lacks stable secondary structures as monomers and has the propensity to form oligomers and amyloid fibrils implicated in Parkinson's disease pathogenesis. However, its aggregation mechanism remains unclear, due to the transient nature and low population of diverse oligomeric intermediates co-existing in dynamic mixtures that hinder their structural characterization by ensemble measurements. By minimizing detection volume and time, our platform directly identifies the beta-sheet containing alpha-synuclein transient species among its dominating unstructured monomers, which could provide unique insights into the amyloid aggregations associated with neurodegenerative diseases.
