The world of dental procedures, particularly root canal treatments, is about to witness a transformative shift. Recently, scientists have innovatively devised the utilization of nanosized robots to resolve persisting issues related to root canals. The focus of this breakthrough is to obliterate bacteria present in infected root canals more effectively, prevent any future reinfection, and salvage the natural tooth.
Unveiling the New Approach to Root Canal Treatments
Root canals often fail to achieve complete success due to lingering bacteria hidden deep within the dentinal tubules, which tend to be overlooked during the procedure. To remedy this shortcoming, researchers are exploring the use of nanosized robots. These microscopic machines navigate through the tubules to neutralize the bacteria.
The technique involves injecting spiral silica nanobots, amplified with a trace of iron, into the tooth’s central canal. Subsequently, a rotating magnetic field is applied, instigating movement in the nanorobot akin to a screw drilling into a wall. Upon reaching the bacterial colony, the nanorobot engages its antibacterial arsenal, employing localized heating among other strategies.
Understanding Nanorobots
Nanorobotics primarily deals with developing machines or robots at the nanoscale. Informally termed ‘nanobots’, these engineered nano machines perform specific tasks and measure around 50 to 100 nm wide. They offer great promise in the realm of drug delivery.
Traditional drugs journey through the entire body before reaching the disease-stricken area. Contrarily, nanotechnology enables direct targeting of the drug to the precise location, enhancing its effectiveness while minimizing potential side effects.
Nanotechnology’s Role in Healthcare
The healthcare sector holds immense potential for nanotechnology application. Nanotech detectors designed for heart attack detection, nanocarriers deployed for eye surgery or chemotherapy, diabetic pads that regulate blood sugar levels, and nanopores that make DNA sequencing efficient, signify just a handful of this technology’s potential uses.
Nanosponges, coated with a red blood cell membrane, act as toxin absorbers and aid in their removal from the bloodstream. NanoFlares, on the other hand, are instrumental in detecting cancer cells in the bloodstream.
Government Initiatives Promoting Nanotechnology
Several government-led initiatives underscore the commitment to advancing nanotechnology. The Nano Science and Technology Mission (NSTM) is an overarching programme launched in 2007 to promote nanotechnology research and development. Its objectives encompass fostering research, developing supportive infrastructure, nurturing human resources, and forging international collaborations.
The Department of Science and Technology established the Nano Science and Technology Initiative (NSTI) in 2001. It concentrates on matters related to infrastructure enhancement, research, and practical programmes associated with nanomaterials including drugs, drug delivery, gene targeting, and DNA chips.
