Active and responsive polymer surfaces

Chem. Soc. Rev., 2010
A central challenge in polymer science today is creating materials that dynamically alter their structures and properties on demand, or in response to changes in their environment. Surfaces represent an attractive area of focus, since they exert disproportionately large effects on properties such as wettability, adhesiveness, optical appearance, and ...

Surface Receptors in the Immune Response

New England Journal of Medicine, 1975
CELLULAR membranes are not simply elaborately constructed containers of cytoplasmic organelles. Rather, the cell surface interface is a complex, highly mobile structure that functions in recognizin...

Surface-Responsive Materials

Science, 2002
Synthetic polymers offer a wealth of opportunities to design responsive materials triggered by external stimuli. Changing the length, chemical composition, architecture, and topology of the chains allows response mechanisms and rates to be easily manipulated; and devices based on the entropy of the chains, surface energies, and specific segmental ...

Multistratum Response Surface Designs

Technometrics, 2001
Response surface designs are usually described as if the treatments have been completely randomized to the experimental units. However, in practice there is often a structure to the units, implying the need for blocking. If, in addition, some factors are more difficult to vary between units than others, a multistratum structure arises naturally.

"Ridge Analysis" of Response Surfaces

Technometrics, 1963
In a 1959 paper, A. E. Hoerl discussed a method for examining a second order response surface. Thii paper provides a mathematically simpler derivation of the technique and proofs of some stated properties.

Cell Response to Surface Stimulation

Nature New Biology, 1972
It has been known for some time that in normal cells growing in culture a relationship exists between cell density and mitotic index1. At a certain saturation density contact inhibition of growth occurs2–4; DNA synthesis decreases and cell division ceases or is drastically reduced.

Phosphatase responsive peptide surfaces

Journal of Materials Chemistry, 2012
The development of interactive surfaces able to respond to biological cues is of interest for the development of next generation biomaterials. We report the design, synthesis and characterisation of an enzyme responsive peptide based surface whose chemical properties change upon catalytic action of alkaline phosphatase (AP).

The response of the surface electrocardiogram to inspiration

Medical Hypotheses, 1985
The waveshape of the electrocardiogram (ECG), as is well known, varies with respiration. This effect was noted from the early days of clinical electrocardiography (1) and has generally been ascribed to changes in the position of the heart. Although it has mostly been regarded as "noise", it is generated by a process and may contain information on the ...

"Repairing" Response Surface Designs

Technometrics, 1972
This note considers a method, recently described by Dykstra, for augmenting existing data in response surface experiments. Examples are given to show how this relatively simple approach can be usefully applied, not only to design repair problems, but to situations in which the experimenter, after reviewing his initial results, decides to change his ...
