The nanoparticle with simultaneous combination of magnetic and fluorescent properties was prepared by immobilization of fluorescein isothiocyanate (FITC) onto magnetic polymeric nanoparticle (MPNP). The MPNP with 41% magnetic content was obtained from incorporating Fe(3)O(4) magnetic nanoparticles (MNPs) into poly(styrene/divinyl benzene/acrylic acid) via(More)
A new bis(diphenylphosphate)diimine ligand (BP1) was prepared and evaluated for its ability for selective detection of deoxycytidine 5′-monophosphate (dCMP). BP1 exhibited off-type fluorescence in the presence of dCMP. The fluorescence of BP1 was significantly quenched upon the addition of 2.5 × 10−4 M dCMP and the detection limit was 1.25 × 10−5 M in(More)
Highly water soluble polymer (DD) was prepared and evaluated for its fluorescence response towards various amino acids. The polymer consists of dansyl hydrazine unit conjugated into dextran template. The conjugation enhances higher water solubility of dansyl hydrazine moiety. Of screened amino acids, DD exhibited selective fluorescence quenching in the(More)
Diimine ligand (DL) 1 significantly exhibited the fluorescence quenching upon binding to guanine. Changing at the para-substituent of the phenyl ring from the hydroxyl to bromo groups reversely enhanced the fluorescence in the presence of guanine. The reverse in the fluorescence selectivity indicated the profound effect of the substituent at the(More)
A new “turn-on” fluorescent chemosensor based on dansyl derivative was prepared for Cu2+ ion sensing. Hydroxyl, imine and azomethine groups in Schiff base derived compound 1 were deliberately introduced for facilitating the binding of Cu2+ ion. Of screen metal ions, compound 1 showed a high degree of selectivity toward Cu2+ ion. Other interfering metal ions(More)
Poly(methyl acrylate) (PMA) of various weight average molecular weights (Mw) were synthesized via the iniferter route and applied for the encapsulation of disinfectant agent (chlorhexidine digluconate; CHD) by using the controlled precipitation technique. The encapsulation efficiency of CHD-PMA nanocapsules suspended in cyclohexane increased from 70 to 100%(More)
