A New Approach for Designing Biodegradable/Bioresorbable Tissue Augmentation/ Reconstruction Devices

2753 – Biomaterials have been widely explored for tissue engineering applications to restore, maintain, or improve tissue function. In particular, biodegradable materials are often used as an initial scaffolding to promote the ingrowth of cells from the surrounding microenvironment and their integration into the implant, with the eventual goal of the biomaterial being replaced by the regenerated...

Porous Materials with High Surface Area

2150 – Membranes have been typically used for filtration, reverse osmosis (hyperfiltration), dialysis, pervaporation, and gas separation applications. A solid membrane can be made of synthetic polymers, natural macromolecules, inorganic compounds, ceramic or metallic materials, and are generally fabricated through sintering, stretching, extrusion, phase inversion and etching, or casting. Porous... Read More

UVA (360-400) and UVB (300-325) Specific Sunscreens

1927 – Sun exposure may result in skin photodamage, primarily due to irradiation by ultraviolet A and B rays (UVA and UVB, respectively). Presently, ranges of UV wavelengths thought to be damaging are considered to be 280-320 nm and 320-360 nm for UVB and UVA, respectively. Compounds or mixtures of compounds that absorb UVA and UVB radiation of these wavelengths are used as sunscreens to prevent... Read More

Hydrogels and Water Soluble Polymeric Carriers for Drug Delivery

1622 – Alginate and other hydrogels are attractive materials for a variety of biomedical applications, including cell transplantation, and drug delivery. In many of these applications one desires to either seed cells into the material, or allow for cellular invasion following implantation into the body. However, alginate is typically used in the physical form of a hydrogel, with small pores (nm... Read More
