Abstract
Methods for sampling an analyte present in a biological system are provided. The methods entail use of particle delivery methods to obtain a sample of an analyte of interest from the system.
Claims22
A method for sampling an analyte present beneath a target skin or mucosal surface of an individual, said method comprising:
- (a) accelerating particles into and/or across said target surface, wherein acceleration of said particles into or across the target surface is effective to allow passage of a fluid sample from beneath the target surface to the target surface, and further wherein said particles are accelerated toward the target surface using a needleless syringe device or a particle-mediated delivery device;
- and
- (b) determining the presence of said analyte in said fluid sample.
A method for use of an inert particulate composition for sampling an analyte present beneath a target skin or mucosal surface of an individual comprising:
- (a) accelerating particles of the particulate composition into and/or across said target surface, wherein acceleration of said particles into or across the target surface is effective to allow passage of a fluid sample from beneath the target surface to the target surface, and further wherein said particles are accelerated toward the target surface using a needleless syringe device or a particle-mediated delivery device;
- and
- (b) determining the presence of said analyte in said fluid sample.
