Putting the lab into the patient to improve chemotherapy success (Day 341)

The fight against cancer is ongoing and I have blogged about this before; see ‘Twin track cancer attack’ and ‘Fighting lung cancer with personalised medicine’. Each new discovery we make shines more light onto effective treatments.

Chemotherapy is a type of cancer treatment that uses one or more chemical substances to kill cancerous cells. It can be used in conjunction with other cancer treatments, or given alone. But as there are over 100 different chemotherapy drugs, our ability to prescribe the most effective drug to treat a particular tumour can be difficult.

MIT chemical engineers have designed an implantable device that can deliver many drugs at once, allowing researchers to determine which drugs are the most effective against a patient's tumor.

MIT chemical engineers have designed an implantable device that can deliver many drugs at once, allowing researchers to determine which drugs are the most effective against a patient’s tumor.

A new device, developed by chemical engineers from Massachusetts Institute of Technology (MIT), US, could provide a solution.

The device, which is about the same size as a grain of rice, is not swallowed or injected, but instead is implanted directly into a cancerous tumour, where it can directly administer small doses of up to 30 different drugs.

Helping our bodies accept drug implants (Day 273)

In recent years we have seen increasing interest in new approaches to drug delivery with greater focus on the efficiency and flexibility of the drugs we use.

robot pillThere are a variety of new methods available to help us do this (some of which I have blogged about before) including: jet injectors; micro-needles; ‘’Injecting’ from the inside’; ‘Using cellular backpacks to deliver drugs’; nano-patches and implants.

Interestingly, the recent Queen Elizabeth Prize for Engineering winner and chemical engineer Robert Langer has spent a good portion of his career looking at improving methods of drug delivery.

Today, I want to highlight a different approach; the use of implants as drug delivery devices. Implants offer several advantages over pills or injections, but often result in immune responses that hinder their performance.

A group of researchers from the Indian Institute of Science (IISc), in Bangalore, India, have developed a biodegradable polymer that acts as an anti-inflammatory agent and allows better acceptance of bio medical implants in the human body.

Robert Langer, chemical engineer, wins Queen Elizabeth Prize for Engineering (Day 253)

My aim in writing this blog has been to ensure the voice of chemical engineering is heard in all corners of the world.

Yesterday was a breakthrough moment in terms of recognition, as Robert Langer – chemical engineer and professor from the Massachusetts Institute of Technology (MIT) in Cambridge, US – was awarded the second ever Queen Elizabeth Prize for Engineering.

Bob Langer’s achievement demonstrates the importance of chemical engineering on a truly global scale.  His pioneering work in drug delivery, tissue engineering and nanotechnology has touched the lives of billions of people.

He has developed a field that, quite simply, didn’t previously exist.  This highlights the most important role that chemical engineers play in society today – improving quality of life for all.

Even chemical engineers can pamper (Day 198)

EyesIn some countries, chemical engineers don’t receive the respect they deserve.

Our contribution is hidden from the public as companies don’t want people to think about the ‘chemicals’ in their products.

I discussed the perception that anything natural is good and anything man-made is bad in my blog ‘Can you lead a chemical-free life?’, which demonstrates that this is not the case.

The US gets a lot of bad press about the public perceptions of science and engineering, but one thing they are getting right is the respect that seems to be increasing for chemical engineers working in the cosmetics industry.

An excellent example of this is the company Living Proof, set up by a team of researchers from Massachusetts Institute of Technology (MIT), including chemical engineering Professor Robert Langer, which initially focused on hair products.

The company has such a strong technological reputation that actress Jennifer Aniston (who I am told is famous for her hair?!) was not only was willing to advertise their products but also invested in the company as a co-owner.

Living Proof is now launching its first skin product – Neotensil – spearhead by another MIT chemical engineering alumnus Dr Betty Yu.

Neotensil uses polymer technology to compress and flatten eye bags.

One less trip to Accident and Emergency (Day 185)

Boy in hospitalChildren aged one to five are notorious for putting things in their mouth. It’s part of their learning process and parents spend a lot of time and effort trying to safety-proof their homes.

There’s some good advice online about how to care for a child that is choking, but there are are other hidden dangers, especially from small button batteries.

It is fairly common for flat, round batteries that power toys, hearing aids, calculators, and many other devices to be swallowed.

Swallowing these batteries has severe consequences, including burns that permanently damage the oesophagus, tears in the digestive tract, and in some cases, even death.

Can chemical engineers change the world? (Day 177)

Change the WorldIn IChemE’s marketing literature you’ll often find phrases like: ‘Join approaching 40,000 peers worldwide to share best practice, find out about new discoveries and change the world.’

I know from talking to colleagues at IChemE the phrase ‘change the world’ has been pounced upon and some believe it is hard to justify.

However, chemical engineers, chemical engineering principles and the fields we work in can and do change the world and you’ll find at least 177 examples in my blog.

If you’re still not convinced let’s take a look at this year’s World Changing Ideas 2014 published by Scientific American. Continue reading Can chemical engineers change the world? (Day 177)

Fighting lung cancer with personalised medicine (Day 93)

DNA and RNARecently I wrote about twins who were creating a better mechanism to release cancer-fighting drugs and about researchers using epigenetics to identify the best treatments for cancers.

Now I have more good news about chemical engineers working to combat lung cancer.

Researchers at the Koch Institute for Integrative Cancer Research at MIT (Massachusetts Institute of Technology) have successfully used RNA therapies to shrink and slow the growth of lung cancer tumours.
