Emerging trends of nanotechnology in biomedical engineeringIAEME Publication
This document discusses emerging trends in nanotechnology for biomedical engineering applications. It begins with definitions of nanotechnology and nanoscale materials. It then discusses various medical applications of nanotechnology including nanorobots for disease treatment and diagnosis. Surgical applications like retinal implants and robotic surgery are also covered. The document concludes by discussing potential concerns from engineered nanoparticles and exposure control procedures.
3D bio-printing involves printing layers of living cells and biomaterials to create organ-like structures for transplantation or research. Charles Hull developed the first 3D printer in the 1980s, and bio-printing was introduced in the late 1990s using "bio-inks" containing living cells. There are three main types of bio-printing: extrusion-based, droplet-based, and laser-assisted. Bio-printing has applications in pharmaceutical testing, artificial organs, wound healing, and "organ chips". While still in development, bio-printing could help address organ shortages and risks of rejection through customized transplants.
Fullerenes are hollow carbon structures made of pentagonal and hexagonal rings. C60 is the most studied fullerene due to its availability and properties. Functionalizing C60 increases its solubility and processability. Some applications of fullerenes include artificial photosynthesis, non-linear optics, cosmetics, surface coatings, and biological uses. Fullerenes are powerful antioxidants that can neutralize many free radicals, protecting cells from damage. They have potential uses in areas where oxidation causes degradation, like food spoilage and metal corrosion. Fullerenes also show promise for targeted drug delivery and reducing friction in moving parts.
Lab-on-a-chip technology integrates laboratory functions onto a single chip only millimeters in size through microfluidics and electronic components. Lab-on-chip devices use materials like glass, silicon, polymers and metals in fabrication processes like deposition, etching, and bonding. They contain microchannels for fluid flow and can integrate nanosensors, allowing portable chemical analysis and detection of small molecules. Applications include point-of-care diagnostics, pollution monitoring, and medical testing. Future advancements will rely on microfluidics and molecular biology with nanotechnology playing a key role.
DNA biosensors use the principles of nucleic acid hybridization and have different forms including electrodes, chips, and crystals. There are three main types - optical, electrochemical, and piezoelectric biosensors. DNA probes can be immobilized onto transducer surfaces through simple adsorption onto carbon, covalent linkage to gold via alkanethiol monolayers, or using biotinylated DNA and avidin/streptavidin complexes on surfaces. The immobilization method depends on the surface and involves covalent coupling or functional group interactions.

This document provides an overview of biomaterials, including:
1) Biomaterials are materials used in medical applications that interact with biological systems without causing harm. They have evolved from first generation inert materials to second generation bioactive materials to third generation materials that can regenerate tissue.
2) Common biomaterials include metals, ceramics, and polymers. Examples are titanium and stainless steel for implants, calcium phosphates for bone repair, and PMMA for dental applications.
3) When interacting with the body, biomaterials can cause reactions like thrombosis, inflammation, and hypersensitivity. Their selection involves factors like mechanical properties, biocompatibility, and cost effectiveness.

Optical nanosensors called PEBBLEs (Probe Encapsulated By Biologically Localized Embedding) are nano-scale sensing devices that encapsulate analyte-specific dyes inside a biologically inert matrix for quantitative measurements inside cells. PEBBLEs come in four types of matrices and can be delivered into cells via four methods. They work by either directly measuring ions and small molecules using fluorescent indicators, or using ion correlation with a silent ionophore and chromoionophore to indicate changes in pH. PEBBLEs protect cells from dyes and dyes from cellular interference while enabling rapid, minimally invasive intracellular measurements of ions and molecules.
The document summarizes the work done at the Liu Nanobionics Lab, which focuses on biomaterials, tissue engineering, and nanotechnology. The lab studies how biomaterials interact with biological systems, develops tissue engineering approaches using scaffolds and growth factors, and modifies material surfaces at the nano-scale to enhance biocompatibility. It also explores techniques like 3D printing and electrospinning to control scaffold architecture for tissue regeneration applications.
