Research style in Nanobiomaterials Laboratory (Okamura Lab)
Nanometer, equals to 0.000000001 meter, is a unit of length in the small world. Nanotechnology is the technology that creates functional materials, devices, and systems through control of matter on nanoscale. Due to the significantly increase of specific surface area of nanomaterials, the interfacial interactions is much enhanced from the view point of chemical reaction. To this end, the miniaturization, weight, and cost reduction of devices has become a possibility. Research in the fields of nanotechnology and nanomaterials engineering has been much developed in recent years.
There are a lot of kinds of polymers used in our daily life, including versatile polymers and bio-friendly polymers (biocompatible and biodegradable polymers). Making use of the knowledge in polymer chemistry and physics, Okamura Lab focuses on the development of innovative, facile and straightforward methods in fabricating two-dimensional polymer nanomaterials (nanosheet, nanodisc, nanoribbon, etc.). Such polymer nanomaterials hold the unique geometries with a larger surface area in two-dimensional contact manner to induce enhanced interfacial adhesiveness. Based on this style, our research is dedicated to the improvement of human health, medical care, and global environment.
The design, fabrication, characterization, and evaluation of nanomaterials in terms of a certain application (optical, odorous, etc.) under the framework of medicine-engineering or interdisciplinary collaboration is always in motion. Our mission is to exploit the unique properties in nanoscale from polymers, and contribute our passion to the society by conveying the research outputs.

The unique characterization of “adherable to anywhere” has been verified for two-dimensional polymer nanomaterials (nanosheet, nanodisc, nanoribbon, etc.). Making use of this property, we aim to develop innovative materials with controllable geometries and physical properties to satisfy the demands from a variety of biomedical applications. Until now, nanomaterials for wound dressing, anti-infective dressing, hemostasis, bone regeneration, drug carrier, diagnosis, etc., have been proposed.

As the old saying goes “a picture is worth a thousand words”, optical microscopy technology has been rapidly developed in recent years, and real time imaging has enabled us to unravel the overall picture of the phenomenon of life. However, the preparation of bio-specimen is still reliant much on the know-how of researchers. In our lab, we employed the advantages of nanoscale thickness and the optical properties of polymer thin films, and proposed “nanosheet wrapping” method to address the problems in microscopic observation. Until now, water-retention effect, sample fixation ability, and possibility for coverslip-free deep imaging has been verified to facilitate the high-quality cell and tissue imaging.

In recent years, more and more cosmetics and personal care products with additional function of aroma or deodorization have been emerged in the market. Nevertheless, the volatility of odor component and the loss of active ingredient due to the flow of sweat always impede the persistence of effect. In our lab, by applying polymer nanomaterials that are invisible and excellent in wear feeling when adhered to skin, we are carrying odor molecules on the surface of nanomaterials in a controllable manner to develop innovative “adherable aroma or deodorization materials”.
