Destructive quantum interference has been shown to strongly reduce charge tunneling rates across molecular bridges. The current consensus is that destructive quantum interference occurs in cross-conjugated molecules, while linearly conjugated molecules exhibit constructive interference. Our experimental results on photoinduced charge transfer in donor-bridge-acceptor systems, however, show that...

Unconjugated bilirubin, conjugated bilirubin, and mixtures of various proportions of each were dissolved in depigmented human serum. These, together with normal and pathologic native human sera, were analyzed for conjugated, unconjugated, and total bilirubin by the Weber-Schalm method. Results were compared with the determination of “prompt direct reacting bilirubin” and of total bilirubin by t...

During the last decade, conjugated polymers have emerged as an interesting class of fluorescence imaging probes since they generally show high fluorescence brightness, high photostability, fast emission rates, non-blinking behavior and low cytotoxicity. The main concern related to most conjugated polymers is their lack of hydrophilicity and thereby poor bio-availability. This can, however, be o...

Since the hypotensive and natrluretic role recently attributed to dopamine (DA) is difficult to test (free DA is usually undetectable in plasma) we measured free and conjugated DA by a newly developed method of hydrolysis of conjugated catecholamlnes in four pheochromocytoma, four primary aldosteronism and 34 essential hypertensive patients subjected to selective venous catheterization or perip...

Hydrogels possessing fine-adjustable and switchable elasticity emulate the mechanical microenvironments of biological cells, which are known to change dynamically during development disease progression. In this study, a supramolecular hydrogel conjugated with gelatin side chains was synthesized. By systematically screening molar fraction host/guest cross-linkers, Young’s modulus substrate fine-...
