Better chemotherapy through targeted delivery

New approach could kill tumor cells in the brain more effectively and avoid side effects.

A schematic drawing of a microneedle pill with hollow needles. When the pill reaches the desired location in the digestive tract, the pH-sensitive coating surrounding the capsule dissolves, allowing the drug to be released through the microneedles.

New drug-delivery capsule may replace injections

Pill coated with tiny needles can deliver drugs directly into the lining of the digestive tract.

This schematic drawing shows a new system that can rapidly and automatically inject zebrafish with drugs and then image them to see the drug effects.

High-speed biologics screen

Engineers devise technology for rapidly testing drug-delivery vehicles in zebrafish.

MIT professor Paula Hammond (right) and Bryan Hsu PhD' 14 have developed a nanoscale film that can be used to deliver medication, either directly through injections, or by coating implantable medical devices.

Advanced thin-film technique could deliver long-lasting medication

Nanoscale, biodegradable drug-delivery method could provide a year or more of steady doses.

MIT engineers created simulations of how a gold nanoparticle coated with special molecules can penetrate a membrane. At left, the particle (top) makes contact with the membrane. At right, it has fused to the membrane.

More than glitter

Scientists explain how gold nanoparticles easily penetrate cells, making them useful for delivering drugs.

The new MIT nanoparticles consist of polymer chains (blue) and three different drug molecules — doxorubicin is red, the small green particles are camptothecin, and the larger green core contains cisplatin.

Targeting cancer with a triple threat

MIT chemists design nanoparticles that can deliver three cancer drugs at a time.

Pills of the future: nanoparticles

Researchers design drug-carrying nanoparticles that can be taken orally

Researchers at MIT and the University of North Carolina created these coated nanoparticles in many shapes and sizes.

Nanoparticles, made to order — inside and out

New research enables high-speed customization of novel nanoparticles for drug delivery and other uses.

Lipid nanoparticles (carrying siRNA) are shown as they are transported inside cells using endocytic vesicles.

Enhancing RNA interference

Helping RNA escape from cells’ recycling process could make it easier to shut off disease-causing genes.

Human breast cancer cells (purple) are targeted by nanoparticles (green) developed by MIT professor Paula Hammond. The particles bind to receptors overexpressed by cancer cells.

Practicing medicine at the nanoscale

New approaches to drug delivery offer hope for new, more targeted treatments.

When the new shear thinning hydrogel (top) is heated to body temperature, polymer chains join together to form a reinforcing network that improves the gel’s stability (bottom).

New injectable gels toughen up after entering the body

These more durable gels could find applications in drug delivery and tissue engineering.

A high-resolution scanning transmission electron microscope image taken at Oak Ridge National Laboratory showing a large hole in the graphene (black region in the center). The image is 32 nm by 32 nm, hence the hole is about 10 nm in diameter. The white on the surface of the graphene is contamination, which is a recurring problem for anyone imaging graphene using this technique.

Tiny pores in graphene could give rise to membranes

New membranes may filter water or separate biological samples.

Ultrasound waves of two different frequencies generate tiny bubbles of water on the skin’s surface. When these bubbles pop, the skin’s surface is lightly worn away, allowing drugs to pass through the skin more easily.

Getting (drugs) under your skin

Using ultrasound waves, researchers boost skin’s permeability to drugs.

This illustration shows how a molten fiber, because of a phenomenon known as Rayleigh instability, naturally breaks up into spherical droplets. Researchers from MIT and UCF have figured out how to use this natural tendency as a way to make large quantities of perfectly uniform particles, which can have quite complex structures.

Dripping faucets inspire new way of creating structured particles

Researchers find new method for making spherical particles, from nanoscale to pinhead-sized — including complex beach-ball-like shapes.
