tiny particles

(Optical Society of America) The precise blending of tiny particles and multicolor dyes transforms gelatin into a realistic surrogate for human tissue.

These tissue mimics, known as "phantoms," provide an accurate proving ground for new photoacoustic and ultrasonic imaging technologies.

A paper by Stanislav Emelianov of UT Austin appearing in OSA's open-access journal Biomedical Optics Express describes an improved method for fabricating tissue phantoms.

WASHINGTON (AP) -- Federal health regulators have found tiny particles of trash in drugs made by Genzyme, the second time this year the biotechnology company has been cited for contamination issues....

(American Association of Pharmaceutical Scientists) Tiny particles that can carry drugs and target cancer cells may offer treatment hope for those suffering with pancreatic cancer.

New research to be presented in November at the American Association of Pharmaceutical Scientists Annual Meeting in Los Angeles reveals that tumor-penetrating microparticles (TPM) have been specifically designed to break through hard-to-infiltrate barriers and deliver drugs more effectively and efficiently than the standard form of chemotherapy such as those injected through a vein.
