Nanoporous Particles Deliver Novel Molecular Therapies to Tumors

(PhysOrg.com) -- Using nanoporous silicon particles, two teams of investigators have created drug delivery vehicles capable of ferrying labile molecular therapies deep into the body. Both groups believe their new drug delivery ...

Four-in-One: Targeted Gene Suppression in Cancer Cells

(PhysOrg.com) -- Diagnosis and treatment in one go: Korean researchers led by Tae Gwan Park and Jinwoo Cheon have developed the basis for a four-in-one agent that can detect, target, and disable tumor cells while also making ...

Microfluidic Devices Capture and Analyze Single Cancer Cells

(PhysOrg.com) -- One of the grand goals in nanotechnology is to develop a single microfluidic device that integrates all of the components needed to perform polymerase chain reaction (PCR)-based nucleic acid analyses. Experts ...

Approval of first RNA interference drug – why the excitement?

Small interfering RNA sounds like something from a science fiction novel rather than a revolutionary type of medicine. But this odd-sounding new drug offers a novel strategy for treating disease by targeting the root cause ...

Self-assembled nanostructures hit their target

A tiny therapeutic delivery system that can control the body's ability to manufacture proteins has been developed by Saudi Arabia's King Abdullah University of Science and Technology (KAUST) researchers.

X-ray imaging reveals a complex core

Macromolecular complexes composed of self-assembling proteins and nucleic acids hold promise for a wide range of applications, including drug delivery, sensing and molecular electronics. Scientists have developed a broad ...

Kryptonite for cancer cells

(Phys.org) —Every available cancer drug is susceptible to resistance, according to Mansoor Amiji, Distinguished Professor and chair of the Department of Pharmaceutical Sciences. Tumors grow more quickly than blood vessels, ...

New African cassava resists devastating viruses

Plant scientists at ETH Zurich have developed a new African cassava preferred by consumers and farmers that is resistant to the two major virus diseases in Africa. Now they want to test the resistant cassava in Africa.

Scientists improve delivery of cancer-fighting molecules

Small interfering RNA (siRNA), a type of genetic material, can block potentially harmful activity in cells, such as tumor cell growth. But delivering siRNA successfully to specific cells without adversely affecting other ...
