The microfibrillar network in gels of poly(γ-benzyl-L-glutamate) in benzyl alcohol

Reversible Gelation in Isotropic Solutions of the Helical Polypeptide Poly(γ-benzyl-l-glutamate): Kinetics and Formation Mechanism of the Fibrillar Network

“…32 For this mechanism, theory and measurements show that the fractal dimension of the gel is equal to the Avrami exponent of its growth kinetics. 32 It so happens that the SANS power laws ("apparent fractal dimensions" in the range of 2.2-2.5) [11][12][13][14] reported for PBLG/BA gels are close to the Avrami exponents reported here, as well as to that of the GP-1 gel (2.4). Nevertheless, we maintain that significant differences exist between these systems so that different mechanisms play a dominant role.…”

Polypeptide-Assisted Organization of π-Conjugated Polymers into Responsive, Soft 3D Networks

“…The q –4 Porod slope reflects a well-defined interface between the fibers and the voids of the gel. The broad peak at d = 1.9 nm was attributed to the distance between the PBLG helices, identical to that found for fibrillar PBLG gels by Cohen . In G1f q –1 and q –4 behaviors were not observed (Figure A, inset).…”

Pursuit of perfection: three‐dimensional ct angiographic “objective quantification” of aortic valve structures for transcatheter aortic valve implantation

“…This distance corresponds to the average spacing between PBLG rods and is consistent with a fibrillar network lacking any long‐range order in which the PBLG rods are packed into a nematic phase. 35, 37 FTIR analysis of these toluene gels also confirms that the PBLGs retain α‐helical conformations in the gel state (Supporting Information Fig. S8).…”
