Capture of HIV-1 gp120 and virions by lectin-immobilized polystyrene nanospheres.


A lectin such as concanavalin A (Con A) was immobilized on the surfaces of poly(methacrylic acid) branches covered with polystyrene nanospheres with a diameter of 360 nm, which were obtained by the free radical copolymerization of styrene with the poly(tert-butylmethacrylate) macromonomer, followed by hydrolysis. Using Con A-immobilized (0.3 microgram/cm2… (More)
