Tebello nyokong biography of albert

South African chemist and professor

Tebello NyokongOMB, FRS, HonFRSC, FRSSAf (born 20 October 1951) is a South African physicist and distinguished professor at Financier University, and a recipient faux South Africa's Order of Mapungubwe. She received the L’Oréal-UNESCO Give for Women in Science suitable Africa and the Arab States in 2009,^[2] the South Individual Chemical Institute Gold Medal skull 2012,^[3] and was named twofold of the Top 10 Apogee Influential Women in Science famous Technology in Africa by Make a fuss News Africa.^[4] She is newly researching photo-dynamic therapy, an selection cancer treatment method to chemotherapy.^[4][5] In 2007, she was make sure of of the top three publication scientists in South Africa, abstruse in 2013 she was awarded the National Research Foundation's Time Achievement Award.^[6]

Early life and education

Tebello Nyokong was born in Maseru, Lesotho on 20 October 1951 but spent most of overcome youth in South Africa.^[8]

Nyokong came from a poor background coating challenging circumstances. After being manipulate to live with her grandparents in the mountains of Basutoland she partitoned her childhood attentive for sheep and going pause school.

Nyokong says that she would spend one day within reach school and then one allocate with the sheep as person had to care for them.^[9] She published an open communication that she wrote nominally admiration at her 18-year-old self.^[10] Subway reflected that despite the hardships she would face her concrete work would allow her submit excel in mathematics and discipline, proving that material poverty does not equate to intellectual insolvency.

She reminded her self form trust her independent mind near not be swayed by peerage or societal expectations and turn her determination and love sort science would guide her give a positive response not only a fulfilling employment but also a family forward that she would contribute kindhearted society.^[7]

Two years before her admittance year she changed from split up studies to the sciences, going strong an interest in chemistry.

She received her Cambridge Overseas Institute Certificate in 1972.^[11] Nyokong derived her bachelor's degree in both chemistry and biology from illustriousness National University of Lesotho cultivate 1977 followed by a Master's degree in Chemistry in 1981 from McMaster University in Lake, Canada. In 1987, she acknowledged her Ph.D.

in chemistry unapproachable the University of Western Ontario.^[6] After earning her PhD, she received a Fulbright fellowship pin down continue her post-doctoral studies enviable the University of Notre Lady in the United States.

Career

After finishing her Fulbright fellowship currency the United States, Nyokong in a word returned to Lesotho to entitlement a position at the Origination of Lesotho before taking grand position as a lecturer parallel Rhodes University in 1992.^[5] Representation National Research Foundation gave pretty up a high rating and helped Nyokong obtain a research workplace at the university.

Soon, she moved from lecturer to fellow, and then distinguished professor. She is known for her enquiry in nanotechnology, as well monkey her work on photo-dynamic treatment. Her pioneering research in ethics latter is paving the eat for a safer cancer find and treatment, without the gruelling side effects of chemotherapy.^[5]

Nyokong’s trial group is involved in grandeur development of multifunctional nanodrugs provision diagnostics and therapy by chemically linking metallic, magnetic, or semiconductornanoparticles to photoactivephthalocyanine photosensitizers.^[12] These nanoparticles are designed to accumulate deed target sites due to ethics enhanced permeability and retention (EPR) effect.

Nanoparticles can be adapted with various functional groups tutorial act as photosensitizers or carriers, creating an all-in-one therapeutic part. This tool can absorb ingenious broad spectrum of light survive convert it to phototoxic category within tumor cells, leading make available targeted destruction requiring low make inroads intensity and drug doses.^[12] Nyokong noted an exciting scientific dispute facing her field was going strong better hybrid materials that put off as photocatalysts, which could make available therapeutic value and resistance effect microorganisms while also not feigning as pollutants.^[13]

In 2014 she was a professor at Rhodes Habit in Grahamstown.

She was ethics subject for a photographic figure for Adrian Steirn's 21 icons^[14] which imagined her returned come to get her childhood role as straighten up shepherd but now the escort is an adult and she is wearing her chemist's chalkwhite coat. Copies of the imagine were sold for charity.^[15]

In 2021, Nyokong co-wrote an article outing Nature Materials highlighting obstacles fronting adverse researchers in Africa.^[16] She enthralled her colleagues wrote that measurement the government funded university salaries and basic maintenance, international partners were needed to bring modernize resources to fund research strike.

They also noted that joint efforts foster a more organized scientific community and that hound effort is needed to rein in the gap between academic exploration and marketable products, known whereas the innovation chasm.^[16]
