A few engineers from Purdue University have designed a practical approach to make surfaces of any therapeutics-related microchannels, tubes, and hollow components, superhydrophobic. With this approach, the efficiency of existing medical devices can be improved significantly.
So far, several hydrophobicity-attaining techniques have been developed that do not allow water to retain on a surface. However, the existing techniques do not hold good to make irregular or non-flat surfaces hydrophobic.
The novel technique makes use of an ultra-fast laser to form etchings on a metallic surface and those etched prints are transferred onto a polymer. The marks on the polymer’s surface—created using the laser technique—are so fine that any sort of water-based fluids will rapidly flow through the channels. The technique will not only improve the efficiency of microfluidic systems but also helps in expeditious cooling of several energy-intensive medical devices.
At present, no technology is available that can create internal superhydrophobic surfaces for microchannels worthwhile.
On a related note, a team of researchers in DGIST, South Korea has designed magnetically controllable biodegradable microrobots. Those bots can be used as carriers in the drug-delivery approach and effective tools to treat cancer by generating effective hyperthermic effect, specifically at a tumor site. The microrobots comprise of magnetic nanoparticles and encapsulated drug stuffed into a structured biodegradable polymer. The doctors and surgeons can assist the microbots to generate heat energy at a particular site by applying an external magnetic field. This approach will evade the possibility of damage to the surrounding healthy tissues, caused by heat therapy. The untethered biodegradable system for creating hyperthermic effect along with drug delivery approach provides dual benefits for therapy.
The engineers stated that apart from generating a hyperthermic effect, specialists could also use fluctuating external magnetic field to direct the movement of biodegradable bots inside the body.
