Ancillary narratives: maids, sleepwalking, and agency in nineteenth-century literature and culture

The limited coverage of servants in nineteenth-century literature may plausibly be ascribed to the tenuous nature of the roles they play in primary texts, and especially to the problematic nature of their agency. This idea is implicit in the arguments of Bruce Robbins, whose The Servant’s Hand remains the most cogent approach to giving servants a palpable role in critical narrative: for Robbins, the agency that acts through the servant ‘prosthesis’ rebounds on the master, granting the servant figure a sometimes exorbitant textual agency. The figure of the sleepwalking maid, and the analogies between sleepwalking and domestic service implicit in it, will help to complicate this picture. In anecdotes of spontaneous sleepwalking, and their subsequent appropriation by mesmerists, maids are cast as non-agents in terms of ownership of narrative: their subjectivity is immaterial to the public fate of the story which their acts generate. But this apparent non-agency is itself derived from their spontaneity; from an autonomous, albeit unconscious, self-will. As such, sleepwalking subjectivity is a gift to paternalism; a mastery it does not have to produce. In conclusion, it is this undetermined quality, rather than a simple lack of agency, that characterizes the maid in the novel, and which continues to exclude domestic servants from critical narrative.

Alanine-rich amphiphilic peptide containing the RGD cell adhesion motif: a coating material for human fibroblast attachment and culture

We studied the self-assembly of peptide A6RGD (A: alanine, R: arginine, G: glycine, D: aspartic acid) in water, and the use of A6RGD substrates as coatings to promote the attachment of human cornea stromal fibroblasts (hCSFs). The self-assembled motif of A6RGD was shown to depend on the peptide concentration in water, where both vesicle and fibril formation were observed. Oligomers were detected for 0.7 wt% A6RGD, which evolved into short peptide fibres at 1.0 wt% A6RGD, while a co-existence of vesicles and long peptide fibres was revealed for 2–15 wt% A6RGD. A6RGD vesicle walls were shown to have a multilayer structure built out of highly interdigitated A6 units, while A6RGD fibres were based on β-sheet assemblies. Changes in the self-assembly motif with concentration were reflected in the cell culture assay results. Films dried from 0.1–1.0 wt% A6RGD solutions allowed hCSFs to attach and significantly enhanced cell proliferation relative to the control. In contrast, films dried from 2.5 wt% A6RGD solutions were toxic to hCSFs.
