Abstract Capillary electrophoretic separation of a mixture of 5'-fluorescein isothiocyanate-labeled single-stranded DNA (normal ssDNA) and its single-base-substituted one (mutant ssDNA) was achieved by using a RAFT-generated polyacrylamide-oligodeoxyribonucleotide block copolymer (PAAm-b-ODN) as an affinity polymeric probe.

Functional RAFT Polymers for Biomedical Applications
To date, efforts have focused on the use of RAFT polymerization for generating block copolymer micelles, vesicles, star polymers, nanoparticles, and capsules as potential advanced drug carriers and also polymer-drug conjugates as prodrugs (Figure 1). 1 This review focuses on the overview of the RAFT process, selection of appropriate RAFT agents

The multi instruments studies of the obtained block copolymers show that the copolymers easily formed as a result of RAFT. Mn,GPC values of the copolymers were between 24,900 g.mol−1 and 74,100 g.mol−1.
- Can PolyDADMAC and polyacrylamide be used as dual flocculants?
- Conclusion TSSs, the reduction of turbidity, COD removal, and ζ potential were studied using different dosages of polyDADMAC and polyacrylamide (PAM) as dual flocculants in treating pulp and paper mill wastewater. Based on the present investigation, polyDADMAC functions as destabilizer, while PAM functions as a bridger.
- Does PolyDADMAC affect flocculation enhancement of pulp and paper mill wastewater?
- PolyDADMAC was selected due to their high charge density meanwhile PAM was high molecular weight. The objective was to investigate the synergistic effect of polyDADMAC and polyacrylamide (PAM) on the flocculation enhancement of pulp and paper mill wastewater.
- Is PolyDADMAC a bridging polymer?
- PolyDADMAC is a highly charged density polymer and has a positive charge in every repeating unit, as shown in Fig. 1. Many researchers agreed that high molecular weight contributes to a bridging effect in the flocculation system , , .
- What is the molecular weight of polyDADMAC flocculant emulsion cationic polyacrylamide?
- The polyDADMAC flocculant used in this study was synthesized with a radical polymerization method and a molecular weight of 8.5 × 10 4 g/mol was obtained using intrinsic viscosity value. ζ potential for this polyDADMAC at pH 7 was 38.20 mV. The emulsion cationic polyacrylamide used in this study was supplied by Global Network Technology Sdn Bhd.
