Poly dimethyldiallylammonium chloride

The most important polyamine with cyclic amine ring on the main chain, is poly(dimethyldiallyammonium chloride) (DMDAC) (13). Due to its cationic charges, poly(dimethyldiallylammonium chloride) can...

DNA has been embedded in LbL films by assembling with polycations like PLL, polyethyleneimine (PEI), and poly(dimethyldiallylammonium chloride) (PDAD) [38-42]. Zhang showed that the DNA released from the film with synthetic degradable polyamine is transcriptionally viable [41]. DNA molecules can keep their structure when incorporated in the film with synthetic polymers [39], making films with DNA suitable candidates for gene delivery. 

Sol-gels containing electroactive species have been used in the development of both amperometric and potentiometric electrodes. Films coated with anionic poly-(dimethyldiallylammonium chloride) (PDMDAAC) and cationic poly(vinylsulfonic acid) were used to concentrate Ru(bpy)3 + and the hexacyanoferrate anion, respectively, for use as amperometric electrodes [208a]. The detection limit by square-wave voltammetry improved by up to 50-fold compared with uncovered electrodes. In Figure 41, curve 1 corresponds to a bare graphite electrode, curve 2 to a sol-gel-covered electrode and curve 3 to a sol-gel-PDMDAAC-modified electrode after 10 min of exposure to Fe(CN)g. ...

Potyrailo and Leach (2006) used the same approach. They evaluated the response of the luminescence from CdSe nanoparticles incorporated into a polymer film to the exposure of polar and nonpolar vapors. It was found that different size nanocrystals provided individual photoluminescence response patterns when the sensor film was exposed to methanol and toluene. Ma et al. (2009) have shown that under optimal conditions the PL intensity of CdTe QDs incorporated in poly(dimethyldiallylammonium chloride) decreased linearly with the increase of formaldehyde concentration in the range 5-500 ppb. The detection limit for formaldehyde was 1 ppb. Other examples of QD-based gas sensors are presented in Table 5.1.

Dubin et al. studied the formation of polyelectrolyte-micelle complexes between poly(dimethyldiallylammonium chloride) and anionic/nonionic mixed micelles by static and dynamic light scattering [21-23]. Dynamic light scattering yields the hydrodynamic radius of the particles investigated (very useful information), especially in combination with SLS, allowing an assessment of the particle architecture. 

This is the reason why we decided to investigate the interactions between blood elements, namely RBC and plasma proteins, and six polycations poly(L-lysine) (PLL), poly(e-lysine) (PEL), diethylaminoethyl-dextran (DEAE-dextran), poly(dimethyldiallylammonium) chloride (PDDAC), poly[2-(dimethylamino)ethyl methacrylate] (P(DMAEMA)) and Q-P(TDAE)n.
