Abstract

High-voltage electrical fields and low production rate limit electrospinning, the electrical charging of polymer liquids, as a means of nanofiber fabrication. Here, we show a facile method of fabrication of aligned three-dimensional nanofiber structures by utilizing high-speed, rotating polymer solution jets to extrude fibers. Termed rotary jet-spinning, fiber morphology, diameter, and web porosity can be controlled by varying nozzle geometry, rotation speed, and polymer solution properties. We demonstrate the utility of this technique for tissue engineering by building anisotropic arrays of biodegradable polymer fibers and seeding the constructs with neonatal rat ventricular cardiomyocytes. The myocytes used the aligned fibers to orient their contractile cytoskeleton and to self-organize into a beating, multicellular tissue that mimics the laminar, anisotropic architecture of the heart muscle. This technique may prove advantageous for building uniaxially aligned nanofiber structures for polymers which are not amenable to fabrication by electrospinning.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Rotary jet spinning produces fibers by centrifugal force pushing polymer solutions through a small orifice, and subsequent jet elongation results in free-floating single-micrometer fibers.

    “Rotary jet spinning produces fibers by centrifugal force, pushing polymer solutions through a small orifice in the spinneret. Subsequent jet elongation results in free-floating single-micrometer fibers (29).”

    From Recreating the heart's helical structure-function relationship with focused rotary jet spinning (2022) · cites this paper as [29]

    The paper’s process description (section labeled Abstract; page unavailable) says centrifugal and hydrostatic pressure propel polymer solution through an orifice, and jet stretching reduces its diameter. It reports fiber diameters of 50–3500 nm, which include roughly one micrometer, but does not describe the resulting fibers as free-floating; it says they were collected on a surrounding collector or coverslips.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
