Welcome to the Molecular Expressions Photo Gallery.
Our portfolio of galleries contains thousands of full color photomicrographs (photographs taken through a microscope) and digital images selected from our many image collections.

It is very easy to view examples from any of our collections. Simply pick the button below that describes the collection of your interest, and you will link to a summary of that collection that includes information about the collection as well as several example photomicrographs.

Each of the small images within the individual collection discussions is actually a link to a larger version of the image. Point and click on the small image to see the larger copy.
The history of pharmaceutical agents is as old as that of man himself. Since the dawn of time, man has used a wide variety of substances to alleviate pain, fight disease, and improve health. Early remedies were often ineffective and sometimes very dangerous and potentially lethal. Today, there are thousands of natural and synthetic drugs that constitute the pharmaceutical palette of modern physicians.

The Molecular Expressions Pharmaceuticals Collection contains over 100 drugs that have been recrystallized and photographed under the microscope. Many of these are presented here and we hope that you enjoy your visit.

The Pharmaceutical links below lead to progressive JPEG images of the drugs that range in size from about 35 Kb up to about 85 Kb.

Aspirin is a salicylic acid acetate with anti-inflammatory and antipyretic properties that also acts as a highly effective non-opiate analgesic. The drug crystallizes in the form of a white, needle-like powder with only a faint odor. In most cases, pharmaceutical aspirin is covered in a casing to buffer the stomach from injury that may occur from ingesting the drug directly. This coating causes the aspirin to digest in the duodenum, instead of the stomach, which is a more neutral-to-alkaline environment. Aspirin may also be useful in reducing the risk of heart attack, stroke, or other problems that may occur when a blood vessel is blocked. Side effects include loss of hearing, confusion, diarrhea, dizziness, and drowsiness.

Chinese Peacock Butterfly

Similar to its avian namesake, the male Chinese peacock butterfly is the more glamorous of the two sexes. Although slightly smaller than female peacock butterflies, males of the species are curiously striking. Sometimes simply appearing deep black, in certain light their wings glow with iridescent green, blue, violet, yellow, and red hues.
