An apparatus, including at least one piezoelectric chip having a working surface, and an opposing at least substantially parallel transducer surface; and at least one interdigital transducer applied to the transducer surface of the chip for generating acoustic energy within the chip in response to an application of an electrical signal to the interdigital transducer; wherein the working surface of the chip is, when in use, in contact with a fluid receptacle to thereby acoustically actuate fluid accommodated within said fluid receptacle, the chip being directly in contact with the receptacle or in contact with a fluid coupling medium that is in contact with the receptacle.

Apparatus for addressing wells within a microarray plate

A method for evaluating Dry Eye Disease ('DED') in a human or animal subject is provided. Thread thinning dynamics of a tear sample of the subject are determined using an acoustically-driven microfluidic extensional rheometry instrument. At least one physical parameter value of the tear sample is calculated based at least in part on the determined thread thinning dynamics. DED is evaluated based at least in part on the at least one calculated physical parameter value of the tear sample. A device for evaluating Dry Eye Disease (DED) in a human or animal subject is also provided. The device includes an acoustically-driven microfluidic extensional rheometry instrument and a processing device configured to evaluate DED based at least in part on the calculated at least one physical parameter value of the tear sample.
