Cooperative effects enhance the transport properties of molecular spider teams [PDF]

open access: yes, 2013
Molecular spiders are synthetic molecular motors based on DNA nanotechnology. While natural molecular motors have evolved towards very high efficiency, it remains a major challenge to develop efficient designs for man-made molecular motors.

Blueprint for a high-performance biomaterial: full-length spider dragline silk genes. [PDF]

open access: yes, 2007
Spider dragline (major ampullate) silk outperforms virtually all other natural and manmade materials in terms of tensile strength and toughness. For this reason, the mass-production of artificial spider silks through transgenic technologies has been a ...

Giant Surface Plasmon Induced Drag Effect (SPIDEr) in Metal Nanowires

open access: yes, 2009
Here, for the first time we predict a giant surface plasmon-induced drag effect (SPIDEr), which exists under conditions of the extreme nanoplasmonic confinement.

Sum frequency generation spectroscopy of the attachment disc of a spider [PDF]

open access: yes, 2021
The pyriform silk of the attachment disc of a spider was studied using infrared-visible vibrational sum frequency generation (SFG) spectroscopy. The spider can attach dragline and radial lines to many kinds of substrates in nature (concrete, alloy, metal,
