The mass of a single cell of the E coli bacterium, they say in the Journal of Applied Physics, is 665 femtograms.
A femtogram is one-thousandth of a picogram, which is one-thousandth of a nanogram, which is a billionth of a gram.
An attogram is one-thousandth of a femtogram, or a thousandth, millionth, billionth of a gram.

 Building a scale sensitive enough to weigh a virus
An attogram is one-thousandth of a femtogram, which is one-thousandth of a picogram, which is one-thousandth of a nanogram, which is a billionth of a gram.
For the latest experiments, the sensitivity of the measurement was increased by reducing the size of the NEMS cantilevers and enclosing them in a vacuum.
The experiments that detected masses in the femtogram range were described in the Nov./Dec. 2001 issue of the Journal of Vacuum Science and Technology by Ilic, Cornell graduate student David Czaplewski, research associate Maxim Zalalutdinov, Craighead, Neuzil, Cornell graduate student Christine Capagnolo and Carl Batt, Liberty Hyde Bailey Professor of Food Science at Cornell.

It weighed a 22 femtogram speck of graphite, by far the smallest mass ever measured.
One femtogram is a million billionth of a gram.
The development marks another advance in the field of nanotechnology, which aims to build machines thousands of times smaller than current microelectronics.

 Application report 003   (Site not responding. Last check: 2007-10-29)
Quantitative NICI MS/MS analysis of PGE1 at the femtogram level
In this application report we demonstrate the use of the CUB 800 for the quantitative analysis of PGE1 at the femtogram level with DG-PGE1 as an internal standard in a complex matrix.
The procedure does not require chemical preparation (enrichment, extraction, etc), therefore sample waste is minimized.

 Beyond 'Nano': A Scale That Weighs Viruses
A one-molecule-thick layer of a sulfur-containing chemical deposited on the gold adds a mass of about 6 attograms, which is more than enough to measure.
The work is an extension of earlier experiments that detected masses in the femtogram range, including a single E. coli bacterium, which recorded a mass of about 665 femtograms.
The experiments that detected masses in the femtogram range were described in the Nov./Dec. 2001 issue of the Journal of Vacuum Science and Technology by Ilic; Cornell graduate student David Czaplewski; research associate Maxim Zalalutdinov; Craighead; Neuzil; Cornell graduate student Christine Capagnolo; and Carl Batt, professor of food science at Cornell.

System allows quantification from picogram to femtogram levels of oxidisable or reducible neurochemical, clinical, pharmaceutical, environmental, and biological compounds
In combination with ESA's patented electrodes, the Coulochem III system is said to be the only electrochemical detector to offer redox capability in a single cell.
Compatible with all HPLC columns and offering the widest choice of operating modes, the Coulochem III system allows quantification from picogram to femtogram levels of oxidisable or reducible neurochemical, clinical, pharmaceutical, environmental, and biological compounds.
