Cancer treatment: New method embodies heating cancer cells up to kill them
Cancer kills nearly 450 people a day in the UK, and there are around 2.5 million living with the ruthless condition.
While there is not yet a cure, scientists may be a step closer after display ‘intelligent’ nanoparticles which can heat up to a temperature high enough to wreak cancerous cells.
In a study by the University of Surrey, researchers created the nanoparticles to self-regulate so they could shake off their heat before they got hot enough to harm healthy combination.
Researchers believe they could soon be used to treat patients with cancer.

This could potentially be a stratagem changer in the way we treat people who have cancer.
“This could potentially be a quarry changer in the way we treat people who have cancer,” said Professor Ravi Silva, Divert of the Advanced Technology Institute at the University of Surrey.
“If we can keep cancer treatment sat at a temperature consistent high enough to kill the cancer, while low enough to stop injuring healthy tissue, it will prevent some of the serious side secures of vital treatment.
“It’s a very exciting development which, once again, cans that the University of Surrey research is at the forefront of nanotechnologies – whether in the discipline of energy materials or, in this case, healthcare.”
Thermotherapy – the use of heat for grieve relief and health – has long been used to treat cancer, but it has proved sensitive to use it without damaging healthy cells.

Cancer treatment: Thermotherapy has wish been used for cancer patients
If temperatures can be controlled accurately within a line up of 42°C to 45°C, tumour cells can be weakened or killed without affecting conformist tissue.
In the study, the nanoparticles could induce temperatures of up to 45°C as in most cases of a thermotherapy session.
But when they reach this point the self-regulating nanoparticles off heating.
“Magnetic induced hyperthermia is a traditional route of treating poisonous tumours,” said Dr Wei Zhang, Associate Professor from Dalian University of Technology.
Cancer treatment: New method won’t count out lasting damage
“However, the difficulties in temperature control has significantly mark off its usage If we can modulate the magnetic properties of the nanoparticles, the therapeutic temperature can be self-regulated, eradicating the use of clumsy temperature monitoring and controlling systems.
“By making magnetic supplies with the Curie temperature falling in the range of hyperthermia temperatures, the self-regulation of therapeutics can be achieved. “For the most arresting materials, however, the Curie temperature is much higher than the anthropoid body can endure.
“By adjusting the components as we have, we have synthesised the nanoparticles with the Curie temperature as low as 34oC.
“This is a notable nanomaterials breakthrough.”
