Carbon nanodots (C-dots), as a new emerging star, have attracted great attention in recent years. Its unique properties have been developed and applied to energy conversion/storage, bioimaging, drug delivery, sensor and other biological related aspects. In this review, we introduce various synthetic methods, basic photoluminscene properties, PL mechanism and then focus on the most recent progress in targeted drug and gene delivery guided by multimode bioimaging technologies in cancer therapy. We also speculate on an outlook towards future developments for their use in bioimaging, drug delivery, sensors, diagnostics and composites.

Carbon nanotubes are well known for their unique physical properties, which depend on the dimensions of the nanotubes. It is imperative to develop methods for positioning, orienting, and controlling the diameter and length of CNTs before they can be used in a broad range of applications. This review will focus on the synthesis of ordered CNTs. A few promising applications that are expected to impact emerging technologies are also introduced.

Nanobubbles formed at a solid-liquid interface have attracted a lot of attention because of their unique physical and chemical properties, and their foundational interests in life science, physics and other science areas. We found that the nanobubbles could be created on TiO₂ coating surface in pure water by the “solvent exchange” method. By using a temperature-controller accessory and a single-probe thermocouple to control the temperature in atomic force microscopy (AFM) liquid cell, we studied the influence of temperature and degassing on the aggregation of nanobubbles on the TiO₂ coatings surface.
