Sɛ yɛbɛka no tiawa a, dɛn ne Nanomedicine?
Fa w’adwene bu wo ti nhwi no nhama bi. Ɛyɛ teateaa dɛn? Afei kyɛ saa nhama no ntwemu apem. Ɛno ne ne kɛse a ɛyɛ ketewaa sen biara, a aniwa ntumi nhu, ɛno ne nea nanometer yɛ. Yɛreka nneɛma nketenkete a ɛyɛ nketenkete araa ma wontumi mfa lab microscope a wɔde di dwuma daa mpo nhu ho asɛm.
Enti, nanotechnology fa nneɛma a wɔde bɛyɛ adwuma wɔ ɔkwan ketewaa bi so ho. Nanomedicine fa saa mfiridwuma no a yɛde bedi dwuma de ahwehwɛ yɛn akwahosan ho haw ahorow ano aduru ho.

Ɔkwan bɛn so na nano mfiridwuma yi yɛ adwuma?
Susuw ho saa kwan yi so. Momma yɛnka sɛ wopɛ sɛ wode krataa bi kɔma w’adamfo bi a ɔwɔ Colombo. Wubetumi de krataa no ama adwumakuw bi a wɔde nneɛma kɔma nkurɔfo a wɔde nneɛma kɔ Sri Lanka nyinaa. Afei ɛbɛfa mmeae ahorow na akɔ baabi a ɛfata.
