Programmed assembly of nanoscale structures using peptoids.

Abstract

Sequence-specific polymers are the basis of the most promising approaches to bottom-up programmed assembly of nanoscale materials. Examples include artificial peptides and nucleic acids. Another class is oligo(N-functional glycine)s, also known as peptoids, which permit greater sidegroup diversity and conformational control, and can be easier to synthesize and purify. We have developed a set of peptoids that can be used to make inorganic nanoparticles more compatible with biological sequencespecific polymers so that they can be incorporated into nucleic acid or other biologically based nanostructures. Peptoids offer degrees of modularity, versatility, and predictability that equal or exceed other sequence-specific polymers, allowing for rational design of oligomers for a specific purpose. This degree of control will be essential to the development of arbitrarily designed nanoscale structures. 5 ACKNOWLEDGMENTS

“…All analyses were performed with R using base functions (lm, p.adjust) and generally the following packages: Rtsne, GGally, pheatmap, ggpubr, broom, formattable, and tidyverse. [64][65][66][67][68][69][70] Dimension reduction techniques included principal component analysis and t-Distributed Stochastic Neighbor Embedding. For the cytokine tSNE analysis, any missing values were replaced with the median of that cytokine level, with respect to the cohort.…”
