Abstract
The present study sought to investigate the physicochemical properties of cationic branched maltodextrins with similar degrees of substitution but different degrees of branching and their siRNA delivery capacity. The results showed that the ratio of α-1,6 glycosidic bonds was significantly increased in the sample treated with dual enzymes. The structural characterization results showed that abundant short chains reassembled by 1,4-α-glucan branching enzyme (GBEs) hydrolysis formed hyperbranched short clustered structure. The absorption peaks that appeared in the FT-IR spectrum confirmed the occurrence of quaternization. The complexes formed by self-assembly of cationic maltodextrins and siRNA were verified by the gel retardation assay and atomic force microscopy, demonstrating a uniform spherical structure with a size close to 300-350 nm. Meanwhile, cationic branched maltodextrins could effectively reduce the change of secondary structure of siRNA. Overall, the results suggested that branched maltodextrins with a cationic surface had significant potential as siRNA carriers.

Abstract
![]()
The kinetics of lambda
carrageenan (λ-car) adsorption/desorption
on/from anchoring layers under diffusion- and convection-controlled
transport conditions were investigated. The eighth generation of poly(amidoamine)
dendrimers and branched polyethyleneimine possessing different shapes
and polydispersity indexes were used for anchoring layer formation.
Dynamic light scattering, electrophoresis, streaming potential measurements,
optical waveguide lightmode spectroscopy, and quartz crystal microbalance
were applied to characterize the formation of mono- and bilayers.
The unique combination of the employed techniques enabled detailed
insights into the mechanism of the λ-car adsorption mainly controlled
by electrostatic interactions. The results show that the macroion
adsorption efficiency is strictly correlated with the value of the
final zeta potentials of the anchoring layers, the transport type,
and the initial bulk concentration of the macroions. The type of the
macroion forming the anchoring layer had a minor impact on the kinetics
of λ-car adsorption. Besides significance to basic science,
the results presented in this paper can be used for the development
of biocompatible and stable macroion multilayers of well-defined electrokinetic
properties and structure.

Abstract
Cationic polyamidoamine (PAMAM) dendrimers are highly branched nanoparticles with unique molecular properties, which make them promising nanocarriers for gene delivery into cells. This research evaluated the ability of hyperbranched PAMAM (hPAMAM)-G2 with a diethylenetriamine core to interact with DNA, its protection from ultrasonic damage, and delivery to alfalfa cells. Additionally, the effects of ultrasound on the efficacy of hPAMAM-G2 for the delivery and expression of the gus A gene in the alfalfa cells were investigated. The electrophoresis retardation of plasmid DNA occurred at an N/P ratio (where N is the number of hPAMAM nitrogen atoms and P is the number of DNA phosphorus atoms) of 3 and above, and hPAMAM-G2 dendrimers completely immobilized the DNA at an N/P ratio of 4. The analysis of the DNA dissociated from the dendriplexes revealed a partial protection of the DNA from ultrasound damage at N/P ratios lower than 2, and with increasing N/P ratios, the DNA was better protected. Sonication of the alfalfa cells in the presence of ssDNA-FITC-hPAMAM increased the ssDNA delivery efficiency to 36%, which was significantly higher than that of ssDNA-FITC-hPAMAM without sonication. Additionally, the efficiency of transfection and the expression of the gus A gene were dependent on the N/P ratio and the highest efficiency (1.4%) was achieved at an N/P ratio of 10. The combination of 120 s of ultrasound and hPAMAM-DNA increased the gusA gene transfection and expression to 3.86%.
