Electrospinning fibers: acoustic barriers and acoustic sensors

The development of new materials and coatings provide also new solutions to problems related to acoustic isolation on architecture, vehicles or aircrafts. Fibrous materials have particularly interesting features for acoustic barriers, as they are usually light, resistant and adaptable to diverse geometries [1]. The sound absorption coefficient is calculated as the quotient between the acoustic… Continue reading Electrospinning fibers: acoustic barriers and acoustic sensors

On July 20th  2017, the U.S. National Institute of Food and Agriculture (NIFA), part of the Department of Agriculture (USDA), announced a $4.6 million grant for research on nanotechnology applied to agriculture and food industry. “Nanotechnology is being rapidly implemented in medicine, electronics, energy, and biotechnology, and it has huge potential to enhance the agricultural… Continue reading Electrospinning: enzyme encapsulation for food industry

Biomedical applications of electrospinning: drug delivery

Electrospinning technique offers numerous possibilities in drug delivery applications, by controlling the material (organic, inorganic, biodegradable or non-biodegradable…), the delivered drug or the loading method. In this article, we present an overview of the drug delivery applications of electrospinning. Fiber materials: Biodegradable and non-biodegradable materials behave differently regarding drug release. Non-biodegradable materials release drug mainly… Continue reading Biomedical applications of electrospinning: drug delivery

Biomedical applications of electrospinning: Tissue engineering

Electrospinning technique has been available since the first decades of the 20th century, but its applications to tissue engineering or drug delivery are relatively new. This can be attributed to the recent automatization of the technique and its availability. In the last few years, modern electrospinning devices allow the user to control the parameters with… Continue reading Biomedical applications of electrospinning: Tissue engineering

Electrospinning, what do I spin?

One of the main parameters of the electrospinning process is the nature and viscosity of the solution. In order to obtain homogeneous fibers, the electrospinning fiber material must be carefully chosen. Each electrospinning solution has unique viscosity and characteristics that influence the thickness and aggregation of the fibers. These parameters will influence the application of… Continue reading Electrospinning, what do I spin?

Electrospinning, an overview

Electrospinning technique was first reported by the Noble Prize John William Strutt, 3rd Baron Rayleigh, in 1897, who observed the effect that electric charge had on water jets [1]. It was studied deeper by Zeleny and patented by Formhals in 1934, who presented a setting for the fabrication of textile fibers using a voltage of… Continue reading Electrospinning, an overview
