Marine Spongin: Naturally Prefabricated 3D Scaffold-Based Biomaterial

Marine Drugs, 2018
The biosynthesis, chemistry, structural features and functionality of spongin as a halogenated scleroprotein of keratosan demosponges are still paradigms. This review has the principal goal of providing thorough and comprehensive coverage of spongin as a

Biomimetic Superhydrophobic Films with an Extremely Low Roll-Off Angle Modified by F16CuPc via Two-Step Fabrication

Nanomaterials, 2022
Superhydrophobicity is the phenomenon of which the water contact angle (WCA) of droplets on a solid surface is greater than 150°. In the present paper, we prepare a superhydrophobic film with a structure similar to the surface of a lotus leaf, which is composed of polydimethylsiloxane (PDMS), zinc oxide (ZnO), a molecular sieve (MS) and 1,2,3,4,8,9,10 ...

Design, fabrication and control of soft robots [PDF]

, 2014
Conventionally, engineers have employed rigid materials to fabricate precise, predictable robotic systems, which are easily modelled as rigid members connected at discrete joints. Natural systems, however, often match or exceed the performance of robotic

Identifying Vessel Branching from Fluid Stresses on Microscopic Robots

, 2020
Objects moving in fluids experience patterns of stress on their surfaces determined by the geometry of nearby boundaries. Flows at low Reynolds number, as occur in microscopic vessels such as capillaries in biological tissues, have relatively simple ...

Wettability influences cell behavior on superhydrophobic surfaces with different topographies [PDF]

, 2012
Surface wettability and topography are recognized as critical factors influencing cell behavior on biomaterials. So far only few works have reported cell responses on surfaces exhibiting extreme wettability in combination with surface topography.

Polymeric fibers with tunable properties Lessons from spider silk [PDF]

, 2011
Making artificial fibers inspired in spider silks is considered as one of the milestones in the field of biomimetics. The interest is usually justified by the outstanding tensile properties of natural fibers, but it is usually overlooked that spider silk

Examination of silver-graphite lithographically printed resistive strain sensors [PDF]

, 2006
This paper reports the design and manufacture of three differing types of resistive strain sensitive structures fabricated using the Conductive Lithographic Film (CLF) printing process. The structures, utilising two inks prepared with silver and graphite

Novel nanostructured hematite–spongin composite developed using an extreme biomimetic approach

RSC Advances, 2015
The characteristic mineral-free fibrous skeletons (made of structural protein-spongin) of H. communis (Demospongiae: Porifera) was used as a structural template in hydrothermal synthesis of hematite (α-Fe2O3) nanoparticles.

Plastron respiration using commercial fabrics [PDF]

, 2014
A variety of insect and arachnid species are able to remain submerged in water indefinitely using plastron respiration. A plastron is a surface-retained film of air produced by surface morphology that acts as an oxygen-carbon dioxide exchange surface ...
