Acrylic polymers have broad applications in the manufacture of paints and paper coatings, emulsion adhesives, plastics, lighting, glass replacements, personal care products and even dental fillings. However, acrylic acid and some acrylate oligomers and monomers adversely affect human health as eye and skin irritants. Exposure to monomers occurs primarily in the workplace via inhalation and derm...

The ideal method of wound closure in children who present to the accident and emergency department with lacerations, is painless, rapid, easy to perform, safe, and results in minimal scarring. Tissue adhesives have relatively recently been used as a “no needle” alternative to conventional suturing. This review reports on the development of tissue adhesives and analyses how close they are to thi...

objectives: the aim of the study was to compare the effect of fifth and seventh generation bonding agent on sealant success. materials and methods: sixty-four school children aged six to nine years received sealants in four permanent molars in a split mouth design, such that each patient received sealant in the first permanent molar with fifth generation bonding agent in one arch and seventh ge...

We present a new manufacturing technology to produce multi-scale compliant feet for use with a novel climbing robot. Climbing robots for space exploration missions may allow scientists to explore environments too difficult for traditional wheeled designs. These climbing robot designs should be able to grasp or adhere to a variety of surface types at multiple angles in order to be effective. To ...

The purpose of this study was to evaluate the sealing ability of four self-etching adhesives placed over blood-contaminated/uncontaminated resected root apices without root-end preparation. Extracted maxillary incisors and canines were randomly divided into four groups of 10 teeth each. After canal preparation and resection of the apex, four self-etching adhesives (Clearfil SE Bond, One-Up Bond...

The development of medical tissue adhesives has a long history without finding an all-purpose tissue adhesive for clinical daily routine. This is caused by the specific demands which are made on a tissue adhesive, and the different areas of application. In otorhinolaryngology, on the one hand, this is the mucosal environment as well as the application on bones, cartilage and periphery nerves. O...

Contemporary medical and dental adhesives often have difficulty sticking to wet surfaces or weaken with long-term exposure to water. Substantial research has been dedicated to finding a means of achieving adhesion in an aqueous environment. A study evaluates the adsorption of catechol relative to other chemical groups as means of gauging how effective they may be as adsorptive groups in adhesiv...

Design and Characterization of Fibrillar Adhesives

A three-dimensional analysis of cracks in adhesively bonded laminates, with debonding around the crack, is presented. The three-dimensional finite element method is based on a hybrid-stress procedure. Effects of the following parametricvariations are studied: (i) relative thicknesses of adhesives, (ii) relative material properties of adhesives and adherends, (iii) ratio of flaw length, to lamin...

Ocular tolerance to cyanoacrylate tissue adhesives was evaluated in rabbits. In the experimental studies, tissue adhesives were implanted intralamellarly, subconjunctivally, and in the anterior chamber. The eyes were examined clinically and histologically at different time intervals. In the cornea and conjunctiva, the adhesive reacted as any inert material. The reaction was considerably less th...
