Poly(4-vinyl pyridine) (p(4-VP)) particles were synthesized using ethylene glycol dimethacrylate (EGDMA) as cross-linker and ammonium persulfate (APS) as initiator in a microemulsion system. The synthesized p(4-VP) particles were modified with various modifying agents. The modification was carried out using N-alkyl quaternization agents such as 2-bromo ethanol (-OH), 4-bromo butyric acid (-CO2H), 4-bromo butyronitrile (-CN) and 2-bromoethylamine hydrobromide (-NH2). The size and charge characterization of particles were done using DLS and Zeta potential measurements, and the modification is confirmed by FT-IR spectrophotometer and titrations. SEM and/or optical microscopy were used for the visualization of particles. The modified p(4-VP) particles were tested for antimicrobial properties against various bacteria such as Staphylococcus aureus ATCC 25323, Escherichia coli ATCC 8739, Bacillis subtilis ATCC 6633.  And the absorption of various species such as metal ions (Co, Ni etc), dyes (Rhodamine 6G, fluorescein sodium salt) and pesticide (paraquat) onto p(4-VP) based particles were also investigated.
