Nanoparticles in Chemical Enhanced Oil Recovery
Nanotechnology in Chemical Enhanced Oil Recovery deals with the application of materials based on nanometer scale to the recovery of difficult-to-access oil from reservoirs. Additional recoveries (after brine flooding) up to 15% of the original oil in place, or higher when combined with smart water or magnetic fields, have been found with formulations consisting of simple nanoparticles in water or brine. The functionalization of nanoparticles and their combination with surfactants and/or polymers take advantage of the synergy of different EOR methods and can lead to higher additional recoveries. The cost, difficulty of preparation, and stability of the formulations are problems that face practical applications.

Nanoparticles in Cancers Immunotherapy
Cancer immunotherapy becomes an important tactic for cancer treatment. Immunotherapy of cancer must activate the host’s anti-tumor response by enhancing the innate immune system and the effector cell number, while, minimizing the host’s suppressor mechanisms. However, many immunotherapies are still limited by poor therapeutic targeting and unwanted side effects. Hence, a deeper understanding of tumor immunology and antitumor immune responses is essential for further improvement of cancer immunotherapy.

Nanoparticles for mRNA-Based Vaccines
The nanodelivery system plays a dual function in RNA-based vaccination by acting as a carrier system and as an adjuvant. That is due to its similarity to microorganisms structurally and size-wise; the nanodelivery system can augment the response by the immune system via simulating the natural infection process. Nanodelivery systems allow non-invasive mucosal administration, targeted immune cell delivery, and controlled delivery, reducing the need for multiple administrations. They also allow co-encapsulating with immunostimulators to improve the overall adjuvant capacity.

Nanoparticles as Electroactive Labels
Nanoparticles are emerging materials with outstanding potential for their use as labels in electrochemical immunosensing. Gold, silver and  quantum dots are the main components of such particles, thanks to their direct electroactivity (redox properties). Protein biomarkers of a variety of diseases, including tumour cells, are the target analytes on which such electrochemical immunosensors have been mostly applied.

Nanoparticle–Graphene based Nanocomposites
Bacterial infections are a leading cause of death in both Europe and USA. The use of antibacterial nanomaterials is a very promising approach to combat the microorganisms due to their high specific surface area and intrinsic or chemically incorporated antibacterial action. Graphene, a two dimensional carbon nanomaterial with excellent mechanical, thermal, and electrical properties, and its derivatives, like graphene oxide (GO) and reduced graphene oxide (rGO), are very good candidates for controlling microbial infections. Nonetheless, the mechanisms of antimicrobial action, their cytotoxicity, and other issues continue imprecise. This review offers select examples on the leading advances in the development of antimicrobial nanocomposites incorporating inorganic nanoparticles and graphene or its derivatives, with the goal of providing a improved understanding of the antibacterial properties of graphene-based nanomaterials.

Nanoparticle–Biomolecule Conjugate
A nanoparticle–biomolecule conjugate is a nanoparticle with biomolecules attached to its surface. Nanoparticles are minuscule particles, typically measured in nanometers (nm), that are used in nanobiotechnology to explore the functions of biomolecules. Properties of the ultrafine particles are characterized by the components on their surfaces more so than larger structures, such as cells, due to large surface area-to-volume ratios. Large surface area-to-volume-ratios of nanoparticles optimize the potential for interactions with biomolecules.
