1. A syringe for obtaining nano-sized components from a solution, comprising:
- a barrel having a barrel interior;
a needle extending from one end of the barrel;
a plunger received in the barrel interior at an end of the barrel opposite the needle;
a filter cartridge maintained between the needle and the barrel, the filter cartridge having at least one membrane having apertures of a first distinct size range and apertures of a second distinct size range, andwherein the apertures of the first distinct size range are positioned on one half of the at least one membrane and the apertures of the second distinct size range are positioned on an opposite half of the at least one membrane, andwherein the apertures of the first distinct size range are larger than the apertures of the second distinct size range.

Abstract
A syringe for obtaining nano-sized components from a solution includes a barrel having an interior, a needle extending from one end of the barrel, and a plunger received in the interior at an end of the barrel opposite the needle. A filter cartridge is positioned between the needle and the barrel, wherein the filter cartridge maintains at least one membrane having apertures of two distinct size ranges, and wherein operation of the plunger to draw the solution into the barrel allows for retention of nano-sized components of a size between the two distinct size ranges.
